Thisstainless steel type T thermocouple gas or air probe from ETI is ideal for measuring air temperatures in fridges and freezers, offices and storage areas. It can be used with a wide range of ETI thermometers.

• Fast response time - less than 0.5 seconds
• Temperature range -75 to +250°C
• Size 4.5 x 130mm
• Manufacturer's part 127-300

This probe from Fluke is ideal for air and non-caustic gas applications. Requires 80TK Thermocouple Module (See order code 85-3673).

• Type-K thermocouple for use in air and non-caustic gas measurements
• Bead protected by perforated baffle
• Measurement range:-40° to 816°C
• One year warranty

This thin humidity/temperature probe is ideal for measuring temperature and relative humidity in storerooms and work rooms. Its exceptionally small diameter of 4mm makes it possible to measure in confined spaces.

The probe is also suitable for long-term measurements and monitoring purposes, by mounting it in a PG gland or clamp, for example (not included). The humidity sensor, measuring relative humidity is long-term stable, condensation-resistant and traceable to international humidity standards, such as ILAC, PTB and NIST.

• Temperature sensor - NTC
• Measuring range: 0 to +40°C
• Accuracy: ±0.3°C
• Humidity - capacitive
• Measuring range: 0 to +100%RH
• Accuracy: ±2%RH at +25°C (2 to +98% RH), ±0.08% RH/K
• Length of probe shaft: 4mm
• Testo type 0572 6174
