High temperature humidity probe

High temperature humidity probe


P/N: 770830 [View large]
• Handheld high temperature probe
• -100...+200 °C / 0...100 %RF
• High accuracy

Humidity and temperature probe HC2-HK40-3000 (length 400mm) is recommended for demanding industrial applications with high temperatures. The fixed 2 m cable can be extended by 1, 2 or 5 m.

The HC2-HK40-3000 is connected via cable art.766840 to Swema 3000/md. Swema 3000/md shows relative humidity, temperature, dew point and mixing ration by weight (water content) in grams of water/kg of dry air.

The probe must be protected by a filter, different filters are available dependent on the measurement application. A denser filter protects better for particles and high air velocity, but makes the time to achieve moisture equilibrium at the sensor longer.
The included filter SP-M15 provides fastest response time and is recommended for use in clean air. For measuring in dusty environments (industry) the filter SP-S15 is recommended. Filter SP-TS15 in Teflon (water proof) is the best choice when you see a risk for water splashes on the probe (salt, marine) or against very fine dust particles.

Available filters for this probe:
SP-M15, art.859865, metal wire mesh, pore size 20…25 μm, -100…+200 °C, max 50 m/s (included)
SP-S15, art.859875, sintered steel, pore size 5 μm, -100…+200 °C, max 70 m/s (option)
SP-T15, art.859869, teflon, pore size 10 μm, -80…+200 °C, max 50 m/s (option)
