Certified Hygrometer/Thermometer +/-3% RH

Simultaneously displays humidity and temp. Displays full-range humidity changes in 1 sec.

Qty: $412.89

Part No. 90800
Traceable Hygrometer/Thermometer Meter
Unit simultaneously displays humidity and temperature. One of the newest and fastest humidity sensors ever developed displays full-range humidity changes in 1 second. Ideal for recording wide humidity variations on a second-to-second basis.
  • Serial RS-232-C output permits connection to any IBM*-compatible computer or datalogger
  • Information can be imported into any existing database and, with the accessory Data Acquisition System (below), captured, displayed on monitor, and stored. (Unit is equipped with a sample program that allows you to store 100 readings; the complete DAS-3* Data Acquisition System is required to transfer these readings to a computer file.)
  • Large display (13/8 in.H) shows temperature and humidity simultaneously
  • Relative humidity resolution is 0.1% with ±3% RH accuracy; range is from 10 to 95% RH
  • Temperature is displayed in (user-selectable) °C or °F with resolution of 0.1°; accuracy is ±1°C and range is 0° to 50°C (32° to 122°F)
  • Memory recalls maximum, minimum, and average readings
  • HOLD button freezes display for later reading
  • An ISO 17025 certificate is provided to indicate instrument traceability to standards provided by NIST
  • Unit measures 11/4L x 3W x 7 in.H (3.2 x 7.6 x 17.8cm); weighs 9.5 oz. (269g)
  • Supplied complete with 1 dia. x 61/4 in.L (2.5 x 15.9cm) probe, 40 in. (101.6cm) cable, and 9V alkaline battery
  • Accessories include 115V adapter, carrying case, and DAS-3 Data Acquisition System (all sold separately, below)

Traceable® Hum./Temp./ Dew Point Meter Complete Description

Traceable unit displays humidity to 0.01%—use for QC, ISO 9000, and R/D
Traceable® Digital Hygrometer/Thermometer/Dew Point instrument, by using a special breed of artificial intelligence, provides a response time of under 10 seconds with a resolution of 0.01%RH, 0.01°F/°C, and 0.01° dew point °F/°C. It samples one-and-a-half times per second. "Fuzzy logic" algorithm pinpoints the exact answer almost instantly.

Fast response with high accuracy
Direct-reading instrument has an accuracy of ±1.5%RH and ±0.4°C. Results are reported in both °F and °C from –40.00 to 220.0°F (-40.00 to 104.0°C) temperature, and from -40.00 to 140.0°F (-40.00 to 60.00°C) dew point.

Certified Traceable to NIST
To assure accuracy an individually serial-numbered Traceable® Certificate is provided from our ISO 17025 calibration laboratory accredited by A2LA. It indicates traceability to standards provided by NIST (National Institute of Standards and Technology).

Clean room and food applications
Fulfills federal CLIA requirements and is ideal for hoods, clean rooms, food storage, process control, incubators, desiccators, drug manufacturing, environmental chambers, corrosion analysis, and inside/outside air monitoring. Four-digit LCD display can be read from 10 feet. Rugged handheld unit is designed for years of service.

Hi/Lo memories, programmable alarms, and data output
Memory recalls both highest and lowest readings in dew point, temperature, and humidity at any time. High and low alarms can be programmed in dew point, temperature, and humidity. When an out-of-range condition is sensed, an alarm sounds and the display flashes. Computer output through the accessory Data Cable permits data to be captured, transferred, stored, and printed.

Size is 5-1/2 x 3-1/2 x 1-1/4 inches. Weight is 12 ounces. Probe length is 7 inches. Cable length is 54 inches. Supplied with 9-volt battery for 1-year intermittent usage or 100 continuous hours. AC adaptor (not supplied) is available. Complete with Traceable® Certificate and ABS plastic carrying case. Replacement battery Cat. No. 1112.

Large, bright, four-digit, LCD display. Easy to use — no wicks to wet, no warm-up, no swinging, just point and read. Rugged ABS (acrylonitrile-butadiene-styrene) exterior designed for years of precise, dependable service.

To ensure accuracy, a 1µm thick, dielectric-polymer layer absorbs water molecules through a thin-metal electrode and causes a capacitance change proportional to relative humidity. A thermistor senses temperature.

A serial numbered certificate is provided from an ISO 17025 calibration laboratory accredited by A2LA to indicate instrument traceability to standards provided by the National Institute of Standards and Technology.
