Water-in-oil monitor Eval

Overview
Evaluation kit for moisture-in-oil measurements including an assembled probe and a test board providing digital (I²C) and analog (0..10 V) outputs. The board is compatible with the Arduino IDE environment and includes a micro USB interface for PC connection.

Included

• Assembled, factory-calibrated HYT271 MK33 module for relative humidity (water activity aw) and temperature measurement
• Evaluation board with analog output and digital interface to PC via micro USB
• Probe assembly (screw-in probe with M14x1.5 thread and 4xAWG26 cable, 500 mm)

MK33-W for oil measurement applications
The iST MK33-W capacitive RH sensor is optimized for oil environments and high-end measurement applications. Measurement range covers 0 % RH to 100 % RH (maximum dew point +95 °C). Typical capacitance is 300 pF ±40 pF (at 30 % RH and +23 °C). Extended temperature operation: -40 °C to +190 °C.

HYT271 module – benefits & characteristics
The HYT271 digital humidity module features a mechanically robust, chemically resistant and condensed-water-tolerant sensing area. It is factory-calibrated and provides processed relative humidity and temperature values via an I²C-compatible digital interface. Linearity error and temperature drift are corrected on-chip to ensure high accuracy across a wide range of conditions.
