Description
The Isotech Drago 4934 is a portable multifunction temperature calibrator covering 30 °C to 250 °C. Its large 65 mm × 160 mm volume works as a dry block, a stirred liquid bath, an infrared blackbody, a surface sensor calibrator or a holder for ITS-90 fixed-point cells, so odd-shaped probes can be calibrated directly in stirred liquid with radial uniformity better than 0.007 °C.
Basic, Site and Advanced versions add a reference-probe indicator, test-thermostat inputs, inputs for units under test, automatic cycling and data logging. It heats from 30 to 250 °C in about 40 minutes, runs on 115 or 230 V AC and weighs 8 kg.
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.
