TESTO 922 Thermocouple Thermometer Type K, 2-Channel, -50 to +1000°C 0563 0922

HVAC technicians and industrial maintenance crews use the TESTO 922 to measure temperatures at two points simultaneously with Type K thermocouples. The dual-channel instrument reads from -50 to +1000°C and calculates the temperature difference between channels, making it suitable for flow and return checks on heating systems or verifying temperature drops across heat exchangers.

Why choose it

The TESTO 922 provides reliable dual-channel temperature measurement with a wide range and high accuracy. The backlit display and audible alarm support work in dim or noisy environments, while the infrared interface allows data printing for documentation.

Ideal use cases

• Heating system flow and return temperature checks
• Heat exchanger performance verification
• Industrial process temperature monitoring
• HVAC commissioning and troubleshooting

Good to know

Probes are not included; the instrument accepts any standard Type K thermocouple with miniature flat-pin connectors. The battery life of approximately 200 hours is based on use without display illumination.
