Description
The Isotech Calisto 4953 is a multifunction temperature calibrator for 30 °C to 250 °C that works as a dry block or, with accessories, as a stirred liquid bath, surface-sensor calibrator, infrared blackbody or ITS-90 fixed-point system. Its 35 × 160 mm calibration volume takes a six-pocket insert, with stability of ±0.03 °C (±0.02 °C in the Advanced version).
The Basic version shows set and block temperature, the Site adds a reference-probe indicator, and the Advanced adds test-thermometer inputs, automatic cycling and secure data logging, so a whole measurement loop can be calibrated in the field.
Argonmark Ltd supplies Isotech instruments across Bangladesh — Dhaka, Chattogram, Gazipur, Narayanganj and the gas fields, refineries, terminals and power plants beyond. Send us the model, range, process connection, output and any hazardous-area requirement, and we will confirm the right configuration, lead time and price.
