Jumbo Thermo-Humidity Meter

Fisherbrand™ Traceable™ Jumbo Thermo-Humidity Meter

Catalog No.11-661-19

Fast-response, solid-state sensors show changes in relative humidity, ambient temperature, and (with probe) external temperature in under 30 seconds. Fisher Scientific™ Traceable™ Jumbo Thermo-Humidity Meter has a jumbo (1.12 in.H) display can be read from 35 ft. (10.7m).

Display is updated once every second and shows temperatures in (user-settable) °F or °C.

  • Humidity range: 25 to 95% RH, with 1% resolution and ±2% (midrange) to ±4% (outside midrange) accuracy
  • Ambient temperature range: -5° to +50°C (+23° to +122°F)
  • External temperature probe (included) reads -50° to +70°C (-58° to +158°F)
  • Resolution to 1° and accuracy ±1°C for both ambient and external temperature readings
  • Dual-recall (minimum and maximum) memory can be displayed or cleared at the touch of a button
  • Permits monitoring conditions overnight, weekends, or during any user-set time period
  • External temperature sensor and cable perform accurately under water
  • Unit is battery-operated, self-contained, stable, and accurate; requires no adjustment or maintenance
