Testo sonda de temperatura/humedad (0636 9735)

The Testo 0636 9735 probe delivers precise temperature and relative humidity measurements in a robust, slim design. Unlike generic sensors, it pairs a fast capacitive humidity element with an NTC thermistor, ensuring reliable readings for HVAC, cleanroom, and laboratory applications.

Highlights

• Temperature range -20 to +70 °C with ±0.2 °C accuracy
• Humidity range 0 to 100 %RH with ±1.0 %RH accuracy
• Rapid response: humidity t90 under 10 seconds
• Durable ABS housing, 12 mm probe head diameter
• 1.5 m cable with Testo proprietary connector

In daily use

Connect the probe to a compatible Testo handheld instrument and insert the 130 mm probe head into the measurement environment. The capacitive humidity sensor and NTC thermistor provide stable, accurate readings across the full range. The slim 12 mm head reaches into ducts and tight spaces, while the 1.5 m cable offers flexibility during spot checks or long-term monitoring.
