TOR-6 Transformer Oil Moisture and Particles Tester

TOR-6 Transformer Oil Moisture and Particles Tester

The TOR-6 transformer oil express tester performs high-precision measurements of moisture content and purity (contamination levels) in both mineral and ester-based oils. It measures water activity (aw) from 0 to 1 with a precision of ±10 % or ±10 ppm at 20 °C and also records temperature. The device assesses oil purity according to ISO 99 (ISO 4406:1999), SAE AS 4059, ISO 87 (ISO 4406:1987), and NAS 1638 standards.
