In the analysis of dissolved gases in transformer oil, TCD (Thermal Conductivity Detector) is the core component for detecting inorganic gases such as hydrogen (H ₂), carbon monoxide (CO), and carbon dioxide (CO ₂). Unlike FID, TCD is a universal detector that responds to both organic and inorgani
After a calibration, the instrument reported "ignition failure" - one of the most frustrating malfunctions in the use of the calorimeter. Fortunately, the HZ-384A manual provides a detailed list of six possible causes of ignition failure, and by troubleshooting in order, the problem can be
With just a gentle press, the experiment will be automatically completed "- this is the opening sentence of the HZ-2000H manual, and it is indeed true. But the premise of "easy pressing" is "correct wiring", and the wiring process is the technical core of dielectric loss tes
Thermal relay calibration is the most common application of high current testers. Many electrical maintenance engineers have to do this job every year, but those who are not familiar with the operational details often have to explore on site for a long time. Organize the complete process and follow
When buying a relay protection tester, salespeople often mention "linear power amplifier" or "switch type power amplifier". Most engineers are confused and do not know how much impact this parameter has on actual testing. HZJB-1200 insists on using high fidelity linear amplifiers
