Frequently Asked Questions - ThermoInspector Laserliner

How to use the thermometer in infrared mode?

Press and hold the trigger button (8) to switch on the laser and perform continuous measurement. The two laser points indicate the measured area. Release the button to freeze the value (Hold).

How to switch from °C to °F?

Press the trigger once, then press the mode button 4 times, then press the trigger again. The unit changes. Repeat to switch back.

What does the green or red LED backlight mean?

Green indicates a safe temperature (<4 °C/40 °F or >60 °C/140 °F). Red indicates the HACCP danger zone (4 °C to 60 °C) where bacteria grow rapidly.

How to measure with the foldable probe?

Unfold the plug-in probe. Briefly press the 'Probe' button (2). Measurement lasts 4 minutes. Press again to freeze the value (Hold). To switch back to IR, press and hold the trigger.

What to do if the display shows 'Hi' or 'Lo'?

These messages indicate that the measured temperature is outside the measuring range (-60 °C to 350 °C). Make sure you are pointing within the appropriate range.

How to clean the device after use?

Clean the probe carefully before and after each use. For the housing, use a slightly damp cloth without harsh cleaning agents or solvents.

When should the thermometer be recalibrated?

Annual calibration is recommended to ensure accuracy. You can contact Laserliner after-sales service for this operation.

Can this thermometer be used for medical measurements?

No, the device is designed for the food industry and surface measurements. It is not suitable for medical diagnostics.

How to adjust emissivity?

Press the trigger once, then press the mode button 5 times. Then use the trigger: brief press for +0.1, long press for continuous scrolling from 0.10 to 1.00. The default value is 0.95.

What to do if the device does not turn on?

Check the batteries: open the compartment and insert two AAA batteries observing polarity. If the problem persists, remove the batteries, wait one minute, reinsert them and try again.

  – Thermal retinal damage, LR <280 kW/(m 3sr) within 10 seconds
• When used for the intended purpose and under reasonably foreseeable conditions, the accessible radiation of the LEDs is safe for the human eye and skin.
• Temporary, irritating optical effects (e.g. dazzling, flash blindness, afterimages, colour vision impairment) cannot be completely ruled out, especially under low ambient light conditions.
• Do not intentionally look directly into the radiation source for longer periods of time.
  – Special safety precautions are not necessary.
• No specific measures are required to ensure the limit values of risk group RG 0 are maintained.

Safety instructions

Dealing with electromagnetic radiation

– The measuring device complies with electromagnetic compatibility regulations and limit values in accordance with RED Directive 2014/30/EU.
- Local operating restrictions – for example, in hospitals, aircraft, petrol stations or in the vicinity of people with pacemakers – may apply. There is a possibility of a dangerous impact on – or interference with – electronic devices.
- The measuring accuracy may be affected when working close to high voltages or high electromagnetic alternating fields.

Laserliner®

Dual laser target mark

The dual laser is a targeting aid to sight the location for the infrared measurement. The temperature is only measured between the two laser points on the surface. Please ensure that the space between the instrument and surface to be measured is free of disturbances (steam, gas, contamination, glass).

Insertion of batteries

Open the battery compartment and insert batteries according to the symbols. Be sure to pay attention to polarity.

Infrared measurement

The laser is switched on and an infrared measurement can be performed by pressing the trigger button (8). Measured values are continually shown by pressing and holding the trigger button.

MIN mode

MIN

Trigger (8) Mode button (3)

1x 1x

MIN mode determines the minimum measured value within a continuous measurement (keep trigger button pressed). The measured value is held for 15 seconds (Hold) after the trigger is released. Pressing the button again will start a new measurement, reset the MIN value and record the lowest measured value.

MAX mode

MAX

Trigger (8) Mode button (3)

1x 2x

MAX mode determines the maximum measured value within a continuous measurement (keep trigger button pressed). The measured value is held for 15 seconds (Hold) after the trigger is released. Pressing the button again will start a new measurement, reset the MAX value and record the highest measured value.

LOCK mode

LOCK

Trigger (8) Mode button (3) Trigger (8)

1x 3x 1x

LOCK mode triggers continuous measurement for a period of up to 60 minutes. With no mode set, measured values are shown continually when the trigger button is pressed (keep trigger button pressed).

Short press (button 8): Value +0.1

An integrated sensor head detects the material/surface-specific infrared radiation emitted by all objects. The level of these emissions is determined by the specific emissivity of the material (0.1/10E to 1.00/100E). After switching on for the first time, the device is preset to an emissivity factor of 0.95, which is suitable for most organic materials and non-metals (plastics, ceramics, wood, rubber, paints, varnishes and stone). For materials with different emissivity factors, refer to the table under Point 10.

Wherever possible, paint or matt black stickers can be applied on non-coated metals and metal oxides, which due to their low, temperature-unstable emissivity are suitable for IR measurement only for a limited extent, as well as on surfaces with unknown emissivity in order to set the emissivity factor to 0.95. If this is not possible, use a contact thermometer.

The emissivity last selected is set after the device is switched on. Check the emissivity setting before each measurement.

8 Probe sensor

To use the probe sensor for a measurement, fold out the probe sensor and briefly press the „Probe“ button (2). The measurement takes 4 minutes. The device then switches off automatically. The measured value is held (Hold) by pressing the „Probe“ button (2) again. Pressing the „Probe“ button (2) once more will restart the measurement. In Hold mode the device switches off after 10 seconds.

It is possible to switch back to infrared measurement while measuring with the probe sensor. By pressing and holding the „Trigger“ button (8) the value from the probe sensor is held and marked with (Hold); infrared measurement starts. By pressing the „Probe“ button you switch back to measurement with the probe sensor.

To measure the core temperature in frozen food, drill a hole and then insert the measuring probe into the product.

In accordance with regulation (EC) 1935/2004, the fold-out probe sensor is designed for continuous contact with food, from the measuring probe up to approx. 10 mm before the plastic casing.

9 HACCP Check

Green LED backlighting

Green LED backlighting indicates safe cooling or frozen state below 4°C (40°F) or a safe holding temperature above 60°C (140°F).

Red LED backlighting

The LED backlighting is red when the measured temperature is between 4°C and 60°C. The product temperature is in the HACCP danger zone.

The backlighting flashes when measuring with the probe sensor.

Above 60°C: Hot food zone

Bacteria are killed by heat above 60°C.

4°C ... 60°C: Danger zone

Bacteria grow rapidly between 4°C and 60°C.

0°C ... 4°C: Cool zone

Bacteria grow very slowly between 0°C and 4°C.

Below 0°C: Freeze zone

No bacterial growth below -18°C
