Description
Isotech semi-standard platinum resistance thermometers are metal-sheathed 100 Ω (IEC 60751) four-wire reference probes covering −200 °C to 670 °C depending on the model. They use handmade platinum coil elements with a short sensing length, are annealed and thermally processed, and drift 0.010 Ω per year.
Straight, angled and 90° bent versions fit liquid baths, dry blocks and portable calibrators; with UKAS calibration the uncertainty can be as low as 10 mK over a narrow range.
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.
