techne portable dry-block calibrators

What we offer?

Techne Dri-block Calibrators Tecal Series which are a convenient, accurate and portable reference heat source used in a wide variety of industrial laboratories and factories. 

Tecal Dri-Block (Dry block) Calibrators cover the temperature range ambient -45°C to +650°C. 

THERMAL CALIBRATION – Tecal Series Portable Dri-Block (Dry block) Calibrators and Accessories

Techne have been manufacturing Dri-block Calibrators since 1965. Tecal Series Dri-Block (Dry block) Calibrators from Techne are a convenient, accurate and portable reference heat source used in a wide variety of industrial laboratories and factories. Tecal Calibrators enable the operator to check and re-calibrate critical thermocouples, resistance temperature detectors (RTD), liquid filled sensors and platinum resistance thermometers (PRT) wherever an accurate, calibrated reference heat source is important for industrial and laboratory processes.

Tecal Dri-Block (Dry block) Calibrators cover the temperature range ambient -45°C to +650°C. With the addition of an optional external chilling source, such as the Techne Flow Cooler and cooling probe, the Tecal 140 peltier cooled Dri-block Calibrators can achieve a minimum temperature of -40°C.

All the models are offered with RS232 communication and can be used with a wide range of inserts to suit different probe sizes. Automatic fan cooling is standard, with accelerated cooling probes also available.

4500 High Accuracy Smart Probe Thermometer

The Model 4500 Series Ultra-High Accuracy Thermometer takes metrology-level temperature measurement to the laboratory, the production floor and the field.

Ultra-high system accuracy is achieved because the thermometer and probe function as if they were calibrated together as a system even though they can be purchased separately. The 4500 System uses coefficients stored in each probe with the Steinhart-Hart algorithm to calculate the exact temperature reading every time you plug in a probe to take a measurement. 

The 4500 series thermometers accept a wide range of plug-in probes equipped with proprietary Smart Probe system. The probes utilise super stable thermistors capable of providing high resolution, fast response and ultra high accuracy.

Features

  • High system accuracy
  • • NIST traceable calibration included
  • • Interchangeable temperature probes
  • • Hand-held flexibility 
  • • Hold reading button 
  • • °C/°F display
  • • Auto shut off
  • • Three decimal place mode
  • • Delta T Function keys
