Description
Description
Compare the Testkey TK2530 and TK2530A thermistor resistance meters by the measurement range required. Both provide six-digit readings, 0.05% basic resistance accuracy and dual-channel comparison. The selected model determines the resistance span and number of ranges.
The two models share the test connections, modes and package. TK2530 provides 1 µΩ–20 MΩ coverage and ten ranges, while TK2530A provides 10 µΩ–2 MΩ coverage and nine ranges.
