Description
The Edgetech RH CAL is a portable, self-contained humidity calibration system for the laboratory or on-site work. It generates relative humidity from 5 to 95% (±0.5%) and temperature from 10 to 50 °C (±0.1 °C), controlled independently, and needs no compressed air or water supply.
A primary-method D2 chilled-mirror sensor in the sample chamber measures dew/frost point from −40 to 60 °C for traceability and closed-loop control, with Automatic Balance Control to correct for mirror contamination. Standard probe ports accept common RH and dew-point probes, and each unit is delivered with a multi-point ISO/IEC 17025 accredited, NIST-traceable certificate.
Argonmark Ltd supplies Edgetech Instruments instruments across Bangladesh — to pulp and paper mills, water and effluent treatment plants, chemical, textile, food and power plants in Dhaka, Chattogram, Gazipur, Narayanganj and beyond. Send us the model, measuring range, process connection, wetted materials and output you need, and we will confirm the right configuration, lead time and price.
