  • Temperature range: -40° to +104°C and -40° to +220°F, with ±0.4°C (±0.4°F) accuracy, 0.1°C resolution
  • RH range: 10 to 95% (basic model), 5 to 95% (instant model); accuracy, ±1.5%; resolution, 0.01%
  • Calculate frost point, latent heat, sensible heat, vapor pressure, moisture content, specific enthalpy, specific volume, specific humidity, mixing ratio, and vapor density from moist air
  • Programmable high and low setpoints for temperature, humidity, and dew point sense out-of-specification condition, sound alarm, and flash display
  • Built-in memory recalls highest and lowest readings; computer output capability† permits data to be captured, stored, and printed
  • Instant model provides humidity readings in <10 seconds; basic model in up to 3.5 minutes



  • Bright, 0.5 in.-high, four-digit LCD is 10 times more readable than glass thermometer sling units or meter scales
  • Microcomputer, solid-state construction eliminates glass breakage, mercury separation, and dial shock damage
  • Tough ABS plastic cases ensure a long life—even in severe lab or harsh plant environments


A certificate is provided to indicate instrument traceability to standards provided by the National Institute of Standards and Technology (NIST™).
