Description
The Isotech milliK is a precision thermometer that reads SPRTs, PRTs, thermistors and thermocouples on two isolated channels plus a 4–20 mA transmitter input, covering −270 to 1,820 °C. Accuracy is 5 ppm for PRTs (3 mK at 0 °C), 2 µV for thermocouples and ±0.005% for current, with 0.0001 °C resolution.
It can also run Isotech baths and dry blocks through a list of set points, log more than 180 days of readings, and with selector switches and software build automatic calibration systems for up to 32 sensors. It runs from mains or AA cells and has Ethernet, USB and RS232 interfaces.
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.
