The Isotech Hyperion 4936 temperature calibrator provides an adjustable isothermal enclosure for calibration purposes. It is part of the award winning Isocal-6 family and with a reference probe can be used with different accessories for Dry Block, Infrared, Surface Calibration and even with ITS-90 Fixed Point Cells for uncertainties to 0.001°C. In Dry Block Mode, the large 65mm diameter block allows for the calibration of either larger probes or for calibrating many sensors simultaneously. Stirred liquid baths are suitable for temperature sensors of all types, sizes and shapes.

Basic Model

  • Digital display of set and nominal block temperature
  • Use with a separate external indicator to compensate for gradients and loading
  • Calibrator does not need calibrating; only the indicator & sensor need re-calibration
  • Cal Notepad software
  • Serial PC interface

Site Model

  • Digital display of set and nominal block temperature
  • Single channel indicator for reference probe
  • Best Practice calibration with established traceability and uncertainty
  • Re-calibration requires sending whole unit in
  • Cal Notepad software
  • Serial PC interface

Advanced Model

  • Digital display of set and nominal block temperature
  • Three channel indicator for reference probe and units under test
  • Advanced features including automatic temperature cycling and logging
  • Best Practice calibration with established traceability and uncertainty
  • Re-calibration requires sending whole unit in
  • I-Cal Easy LOG software & built-in web server
  • Ethernet & USB host PC interface

Application Notes

Here's how some of our customers used this product.

Calibrating Odd-Shaped Probes

The Background: Our customer manufactures custom RTDs. They seek a means to calibrate these sensors so they can include a certificate of calibration when sending them to customers.

The Problem: These custom RTDs have a variety and shapes and sizes which make them difficult to calibrate with traditional dry block calibrators.

The Solution: We recommended the site version of the Isotech Hyperion liquid bath calibrator. The site version provides the customer with a comparison calibration of the site probe and indicator against the sensor under test. This allows the best results as the site probe is placed in very close proximity of the probe and this gives a very stable and accurate result.
