NRYH410 Insulating Oil Moisture Tester is an automatic trace moisture testing instrument based on Karl Fischer Coulomb titration. As a professional Insulating Oil Moisture Tester, Insulating Oil Moisture Tester uses a 7inch LCD color touch screen for intuitive operation and automatically calculates and displays moisture content following Faraday's Law. The instrument completes electrolyte balance and sample testing automatically, supporting multiple result display modes and data management, which is specially used for accurate trace moisture detection of insulating oil and other industrial materials.

Product Advantages
1. High detection sensitivity of 0.1ug H₂O reduces repeated calibration and sampling, cutting down reagent and labor consumption.
2. Wide accuracy range minimizes test deviation, avoiding unqualified product risks and retest losses.
3. Long life electrolyte system (100ml electrolyte reacts with ≥1g water) lowers reagent replacement frequency and material cost.
4. Automatic balance and test functions reduce manual operation time, saving onsite labor input for continuous testing.
Application Scenarios
1. Moisture detection of insulating oil in oil filled electrical equipment.
2. Moisture testing in petroleum and chemical production processes and finished products.
3. Trace moisture analysis of pharmaceutical, pesticide and mineral raw materials.

FAQ
1. Q: When does the electrolyte of NRYH410 Insulating Oil Moisture Tester need to be replaced?
A: Replace the electrolyte when the cathode chamber produces strong bubbles, turns reddish-brown, the titration lasts over 30 minutes without stability, or no obvious iodine is generated on the anode. For example, if the tester runs for 2 hours continuously and the endpoint cannot be reached, the electrolyte should be replaced immediately.
2. Q: How to deal with the "over-iodine" status after replacing the reagent of NRYH410 Insulating Oil Moisture Tester?
A: Inject 10μL pure water with a 50μL syringe to adjust the reagent balance. When the reagent color becomes light, control the injection amount until it enters the water state, then calibrate with 5μL pure water before formal sample testing.
