Description

The PTB 600 Dry Block temperature calibrator offers industry-leading performance in an easy to use portable package with a wider range from 33 to 650 ºC. It is ideal for the calibration of Thermocouples and platinum resistance thermometers.  It has been designed for fast heating and cooling for convenient use in field.

The PTB 600 can also be used for Calibrating Infrared Sensors and Surface Temperature Sensors by using the optional inserts.

The new PTB 600 comes in two different models: TS and TC
-PTB600-TS Temperature Calibrator
-PTB600-TC Temperature calibrator with inputs for reference sensor and sensor-under-test

Deeper Immersion depth of 185 mm for large diameter temperature sensor testing

One of the unique features of the PTB 600 is a much deeper immersion depth compared to other products in the market place. The 185 mm immersion depths allow for accurate testing of  larger diameter temperature sensor ( 16-17 mm) and temperature switches using long bulbs which require full immersion.

Fast and accurate calibration

Although featuring a large calibration volume of 35 x 185 mm,  the PTB600 heating block technology allow for fast heating and reduced time to stability. This translate in reduced cost of calibration, less downtime and less man power. All in all it saves money.

Interchangeable multi-holes inserts

The PTB600 uses interchangeable multi-holes inserts. The standard range of inserts accommodate most of the standard temperature sensors. Custom inserts are available on request to accommodate non standard temperature sensor testing.

Light and easy to carry with only 8 KGs of weight

We have thoroughly included the weight in our design and have developed new techniques and used different materials  that have made the PTB 157 temperature calibrator lightweight and easy to carry on site without compromising its quality, durability or functionality.

Automatic Switch/Thermostat Test function ( TS and TC version)

Set your automatic ramp ( slope) with up to 0.1ºC per minute rate. The PTB 157 will store for you the contact open and closed. No need for any additional multimeter.
Maximise your time and perform other tasks while the PTB will do the job for you.

Highest Accuracy ( TC Version) to 0.15 ºC

The TC version is equipped with an built-in high accuracy reference input to be used in conjunction with our SRS ( semi standard PRT)- This feature allows the PTB-TC to perform calibration
with an higher degree of accuracy.- It also eliminates most of the error due to stem conduction and different load

A special 90ºC angled external reference sensor is designed to accommodate calibration of sensors with transmitter head- It provide maximum clearance to the top of the calibrator-
Our SRS external reference sensors are especially designed to improve the performance of our PTB series.
The size and length of the external reference sensors have been chosen to provide best performance on the TC version.  A special linearization/ calibration with the built-in reference input provides maximum reading accuracy better than 0.15 ºC

The user can decide to read with the built-in reference sensor or the more accurate angled external SPRT. The Internal sensor and external sensor readings are independent pf one another

Reading of Sensor Under Test ( TC version)

The PTB600-TC is equipped with a built-in accurate measurement input for sensors under test which enable measurement of RTD and TC. The User can compare the reading of the unit under test to one of the external or internal reference sensor. There is no need to carried on field an additional external hand held thermometer.

EIUK Calibration Software

EIUK is a versatile calibration software that is supplied as standard together with any PTB Temperature Calibrators. The software allows for easy calibration of all kind of temperature sensors, such as RTD´s, thermocouples, and thermo-switches.
