PALMER WAHL RTD THERMOMETERS

RTD THERMOMETERS

 

Heat-Prober® Platinum-RTD Thermometer System

  • Exceptional  Accuracy and Long-term Stability in a Versatile System of Meters and Interchangeable  Probes
  • Meter accuracy ±0.1°F ±1digit
  • Complete tracing of the platinum standard DIN 43760 to 0.1F conformity over the entire  temperature range
  • Readings updated 2.5 times per seconds
  • Maxi-Temp®  holds peak temperature reading
  • Tough, drop tested assembly with snap-in connector

Wahl invented the portable  Platinum-RTD thermometer (Pat.No.4,059,309) to provide exceptional accuracy and conformity  in laboratory and industrial applications.

Thousands of Heat-Probers are used  by the petrochemical, food, photographic, aerospace, electronics and nuclear power  industries, as well as by the U.S.military. They make critical temperature measurements and  calibrate installed sensors and other instruments.

The performance of Wahl meters is  warranted for three years against defects in parts and workmanship.

Fast response platinum probes are  interchangeable without recalibration.

 

700M Thermistor Thermometer

  • Resolution  of 0.01°C/°F, with matching sensitivity
  • Meter  Accuracy of 0.02°C
  • System  Accuracy of 0.04°C
  • Measurements  from -1.00 to 60.99°C (30.00 to 141.80°F)
  • Large  0.33" LED display is easy to read
  • Low  drift of 0.02°C per year for long-term accuracy
  • Rechargeable  battery with 8 hours continuous use
  • FM  approval for use in hazardous environment

The accuracy and resolution of  Wahl's 700M Portable Thermistor Thermometer  make it an ideal instrument for  precision measurements in pipeline oil monitoring, chemical processing, biological testing  and research, and many other production, processing, and laboratory applications.

The handheld instrument provides a  resolution of 0.01°C/°F and an accuracy of ± 0.02°C within the temperature range of  -1.00 to +60.99°C (30 to 141.8°F). Accuracy is traceable to NIST, with an optional test  report for your quality assurance.

The system interchangeability and  accuracy of Wahl's 700M meter with both the LN0255 and LN0255A probes are shown in the  table at left. A system accuracy of ± 0.04°C is obtainable.

The microprocessor-based 700M is  barely a handful. It is only six inches in length and weighs 12 ounces. Measurements are  displayed on a bright red 0.33" LED, making it especially effective in indoor and  low-light conditions. A low drift range of 0.02 per year provides long-term accuracy.

The meter operates on an internal  battery pack with eight hours of continuous operation between charges.

The 700M is intrinsically safe and  Factory Mutual approved for hazardous environments. The meter design is similar to the  platinum meter Model 392M Heat Prober described .

Humidity / Temperature Meters

HTS30 High-speed System

  • Fast  response humidity sensor with 5-sec. time constant
  • 0 to  100% RH, -40 to +176°F
  • Not  affected by moisture condensation
  • Applications:  plant maintenance, air conditioning installation and maintenance, checking humidity levels  and temperature in process areas, measuring moisture content in pager

This handheld humidity instrument  system, comprised of a meter and probe, uses a thin film sensor for extremely fast  measurements. In operation, the film absorbs moisture, changing its capacitance proportional  to the relative humidity. The resulting linearized data is displayed in percent RH.

Simultaneous with the RH reading,  temperature is measured with 0.1° resolution over the -40 to +176°F temperature range.  Temperature measurements employ a high precision, 100 ohm, platinum RTD film sensor element  mounted in the same location as the humidity sensor. A plastic grid protects the sensors  against damage. Models are available with either Fahrenheit.

HTM34 Pocket-Size Meter

  • 6.25  × 2.24 × 1.06 in., 8.8oz.
  • 0 to  100% RH, -4 to +140°F or -20 to +60°C
  • 3-1/2  digit,3/4-in. high LCD readout
  • Hold  button provides measurement retention

Shirt pocket size for easy  portability, the HTM34 has a retractable probe that slides out of the meter case for  quick, easy checks of relative humidity and temperature in laboratory or industrial  environments
