Traceable™ Relative Humidity/Temperature Meters


Fisher Scientific™ Traceable™ Relative Humidity/Temperature Meters allow you to monitor air conditions in environmental chambers, chemical storage areas, cleanrooms, incubators and stockrooms.


  • Humidity range: 25 to 95% RH, Accuracy: ±2% (midrange) to ±4% (outside midrange)
  • Continuously and simultaneously display relative humidity (11-661-11) or humidity/temperature (11-661-12) in extra-large, 0.62 in.-high (1.5cm) digits
  • Made from high-impact, chemical-resistant ABS plastic


With Temperature Readout

  • Temperature readout in °C or °F; ranges from 0° to 50°C (32° to 122°F) with ±1°C/°F accuracy
  • Measures 0.75L x 3.25W x 7 in.H (2 x 8 x 18cm)
  • Net weight: 5 oz. (142g)
