ISIS dry block -100°C (200/240V)
The Isis Dry Block offers operation to temperatures as low as -100°C, and is the only block bath working to such a low temperature. Now it is possible to calibrate temperature sensors such as PRTs, Thermocouples and Thermistors at ultra-low temperatures without the need for a liquid bath.
Portability and Safety
Unlike a liquid bath the Isis requires no costly, or hazardous fluids and offers greater portability. This will be of particular value to calibration engineers working on site with low temperature freezers as encountered in pharmaceutical, aeronautical and food environments.
The minimum operating temperature is less than stirred liquid laboratory calibration baths and users in laboratories will also benefit by avoiding the ongoing need for expensive fluids.
The maximum operating temperature is 40°C, a little higher than the minimum operating temperature of Isotech Hot Blocks. This permits covering the range from -100°C to 650°C or higher with just two Isotech blocks.
By limiting the maximum temperature the reliability and operating life of the cooling engine is maximised, and has been agreed in consultation with the licensee of the cooling technology.

Labcal-PRO Precision Thermometer
The Labcal PRO from Labfacility is fully characterised for Pt100 sensors and all major thermocouples J,K,N,T,E,R,S and B. Exceptionally stable automatic cold junction compensation with a rejection of 100:1 is incorporated for thermocouple ranges. Alternatively, external or manual referencing can be selected as required.
Displayed values and user information are indicated on a bright clear OLED screen with diffused backlighting. Data can be displayed in °C, °F, K, Ω or mV as required; nine front panel push keys, the only user controls, are used in conjunction with the display screen. It is this arrangement which makes for very simple and 'friendly' operation.
Resolution is a user selectable 0.001 or 0.01°C for Pt100 sensors and 0.1°C for thermocouples. All computations are performed digitally without drift. Overall stability is optimised by utilising only the highest quality components including high precision, expensive metal film resistor networks.
There are four input ports, two for thermocouples and two for 3 or 4 wire Pt100 sensors; the instrument automatically recognises 3 or 4 wire configurations.
The Labcal PRO can accept two Pt100 sensors and/or two thermocouples of similar or different types (J,K,N,T,E,R,S and B). The measured temperature can be displayed directly from one of the inputs or differentially between similar or different inputs. Differential temperature and the two individual channel temperatures are displayed simultaneously.
Individual calibrated sensors can have up to 10 appropriate calibration values programmed into the Labcal PRO. The instrument then digitally self-calibrates to the associated probe over the range embraced in the calibrated values used; the temperature readout is 'corrected' accordingly.
