Frequently Asked Questions - 825-T2 Testo

What is the measurement range of the Testo 825-T2?

The infrared measurement range is -50°C to +250°C, with a maximum of 500°C for up to 5 seconds.

How do I change the battery?

Open the battery compartment, remove the old batteries, and insert two new AAA alkaline batteries, observing correct polarity.

What type of battery does it use?

It uses 2 x AAA round cells (alkaline recommended).

How do I clean the lens?

Clean the lens with a cotton bud moistened with water or with compressed air. Avoid solvents.

What is the emissivity setting and how do I adjust it?

Emissivity can be adjusted from 0.20 to 1.00. Use comparison measurement or reference material to set the correct value.

Can I measure frozen food?

Yes, for core temperature measurement in frozen food, use the pre-borer (available for models T3/T4). For the 825-T2, use the contact side if equipped.

What does the optical alarm indicate?

The optical alarm (LED) indicates when the measured temperature exceeds or falls below set limits, complementing the audible alarm.

How do I attach the TopSafe?

Slide the instrument into the TopSafe protective casing until it clicks. Ensure the openings are greased for IP67 protection.

How long is the warranty?

The Testo 825-T2 comes with a 2-year warranty.

What is the IP rating?

With the TopSafe attached, the thermometer achieves IP67 protection against dust and temporary immersion.

Note: The IP 67 protection class is guaranteed only inside the closed TopSafe. If the instrument is kept immersed for a longer period of time, apply grease to inside openings of TopSafe (see arrows).

Battery needs to be changed.

Observe correct polarisation of batteries/rechargeable batteries.

Refer to reference material for the emissivity of the substance to be measured or determine via comparison measurements.

Comparison measurement: 1. Surface contact measurement at one point: 2. Infrared measurement on the same point. 3. Keep changing until readings 1 and 2 are the same.

The emissivity in testo 826 is set at 0.95 which is ideal for measurements on food or on coloured packaging. Use testo adhesive tape Part no. 0554.0051

( = 0.93) on objects with an emissivity below 0.2, e.g. shiny metallic objects, for non-contact measurement or only measure with the contact side.

Beachten:

- Use the pre-borer supplied when measuring the core temperature in frozen food (testo 826 T3/T4). Then place the measuring tip in the object to be measured (Fig. 2).

- Risk of injury from measuring tip (testo 826 T3/T4)

- Maximum ambient and operating temperature (e.g. protect instrument from sunlight)

- The instrument needs an adaptation time of 15 minutes for infrared measurement if the ambient temperature changes (change of location, e.g. measurement inside/outside).

Attention:

- Heat on the heat sensor

- Sharp edges - Do not damage cross-band tip (testo 825 T3/T4).

- Dirt on the lense

Cleaning the lense:

- Clean with cotton buds (made moist with water) or with compressed air.
