Product Overview

The THWD-3 CAL D from Amprobe Instruments is a relative humidity temperature meter. The THWD-3 uses a precision capacitance sensor to deliver accurate performance with long term stability. This high accuracy instrument measures the full range of relative humidity from 0% to 100% and features an exceptionally wide ambient temperature measurement range from -20°C (-4°F) to 60°C (140°F). The sensor is mounted on a long shaft extending from the top surface of the unit making probing into ductwork and hard to reach areas more easy. The large LCD displays two measurements simultaneously with a full range of display options including hold, min, max, dew point (DP) and wet bulb (WB).
  • Calibrated with data meter, dual display, dew point, wet bulb & auto power off
  • Extended probe stem to easily access air ducts, altitude up to 2000m & min/max readings, data hold
  • Capacitive sensor with protective cover, sample rate 2.5times per second
  • 9V battery, NEDA 1604 or JIS 006P or IEC6F22, 85hours continuous (with alkaline battery)
  • Humidity range from 0% RH to 100% RH, 5% RH to 95% RH at ±3% RH, 23°C accuracy
  • Resolution of 0.1%RH, 180sec humidity and 10sec temperature response time
  • Temperature (dry bulb) -20°C to 60°C at ±0.8°C accuracy
  • Temperature dew point (DP) is -20°C to 60°C at ±0.8°C accuracy
  • Temperature of web bulb (WB) of -20°C to 60°C at ±0.8°C accuracy
  • Dimension of 240mm x 54mm x 34mm, 180g weight
