Product information

Description

The Testo 835-T1 Industrial Thermometer is a handheld infrared thermometer with a built-in display, designed for temperature measurement from -30 °C to 600 °C. The unit uses the Celsius scale and is powered by a standard AA battery. Its compact housing (193 × 166 × 63 mm) and black-and-grey casing provide a practical tool for HVAC, refrigeration, process checks and maintenance tasks where non-contact and contact temperature readings are required.

Advantages

The device combines infrared and contact measurement capability, enabling users to measure surface temperatures non-contact and to connect optional sensors for direct-contact readings. A 4-point laser marking indicates the measuring area to reduce incorrect measurements, while 50:1 optics let you measure small targets from a greater distance. The backlit display and simple menu with a joystick make on-site operation straightforward. Data storage for up to 200 readings, min/max values, adjustable thresholds and visual and acoustic alarms support inspection and fault-finding workflows.

Suitable for

HVAC system diagnostics and maintenance
Refrigeration inspections and monitoring
Industrial process checks and quality control
Surface temperature surveys and building envelope checks

Key specifications

Measurement range: -30 °C to 600 °C
Temperature scale: Celsius (°C)
Optics / distance-to-spot ratio: 50:1
Laser targeting: 4-point laser marking
Display: integrated backlit display for readings and menu
Power supply: AA battery
Housing dimensions: 193 × 166 × 63 mm
Color: black and grey casing
Data memory: up to 200 stored measurements; min/max recording and adjustable thresholds with alarms

How to use

Aim the infrared thermometer at the target surface, ensuring the measuring distance corresponds to the optics (50:1) so the target area is fully within the measuring spot. Use the 4-point laser to position the instrument and read values on the integrated backlit display. For contact measurements, connect an optional temperature probe to the device and follow the on-screen menu to switch to contact mode and select the appropriate emissivity setting. Use the joystick to navigate the menu, set thresholds, and save measurements as required.

Usage recommendations

For accurate non-contact readings, ensure the target area is larger than the measured spot and select the correct emissivity value for the material. Use the contact probe when surface emissivity is uncertain or when more precise contact measurement is required. Store recorded data and analyze it with the manufacturer’s software for trend checks and detailed reporting.
