Frequently Asked Questions - 825-T1 Testo

How do I change the battery in the Testo 825-T1?

To change the battery, replace the 2 AAA cells. Observe correct polarity as indicated inside the battery compartment. The battery type is 2 x AAA round cells.

How do I adjust the emissivity on the Testo 825-T1?

Press both buttons simultaneously to enter emissivity adjustment mode. Use the up/down buttons to set the emissivity between 0.2 and 1.0. For most food, a setting of 0.95 is recommended.

How to clean the lens of the Testo 825-T1?

Clean the lens gently with a cotton bud moistened with water or use compressed air. Avoid scratching the lens.

Can the Testo 825-T1 measure liquids?

Yes, it can measure surface temperature of liquids. For accurate readings, ensure the measurement spot is not shiny (use emissivity tape) and avoid steam.

What is the measurement accuracy of the Testo 825-T1?

The accuracy is ±1 °C + 1% of the measured value. Between -30 °C and 99.9 °C, the accuracy improves to ±0.5 °C.

How do I switch between Celsius and Fahrenheit?

To switch units, press and hold the button (or a combination) as indicated in the manual. Typically, holding a button for a few seconds toggles between °C and °F.

What does the IP67 rating mean for the Testo 825-T1?

IP67 means the instrument is dust-tight and can be immersed in water up to 1 meter for 30 minutes, but only when the TopSafe protective cap is closed properly.

How long does the battery last?

Battery life is approximately 20 hours of continuous operation with the laser on. Actual life may vary depending on usage.

Can I measure frozen food with the Testo 825-T1?

Yes, but for frozen food core temperature, use the pre-borer accessory (for models 826 T3/T4). For surface temperature, infrared measurement works directly.

Is the Testo 825-T1 covered by warranty?

Yes, the instrument comes with a 2-year warranty from the date of purchase. Keep the receipt as proof.

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.
