Status: Current Production (most models). We repair and calibrate the full range.
Common Hioki Memory Recorder / Data Logger Problems We Fix
- Input channel dead, noisy, or reading wrong — often after an overvoltage or transient event
- Won’t save or recall data / internal memory or storage media failure
- Display or touchscreen not responding, cracked, or dead
- Battery won’t hold a charge / won’t power on (portable models)
- Temperature readings off — thermocouple reference junction drift
- Won’t communicate over USB, LAN, or wireless
- Won’t trigger / capture timing wrong — trigger circuit faults
- Power supply faults on benchtop models

Frequently Asked Questions
How much does Hioki memory recorder / data logger repair cost?
Repairs start with a flat evaluation fee that’s credited toward your repair cost. After we diagnose the instrument, you get a firm quote before any work begins — no surprises.
How long does the repair take?
Most Hioki repairs are finished within 5–10 business days of arrival, with expedited turnaround available if you need it back fast.
One of my input channels is dead or reading wrong — can you fix it?
Yes. Input channel module damage from overvoltage or transient events is one of the most common faults we repair, and channels are restored to full measurement accuracy.
My readings are drifting or out of spec — can you recalibrate it?
Yes. We verify every critical parameter against our reference standards and return the instrument with NIST-traceable results on a certificate.
My temperature readings are off — is that repairable?
Yes. Thermocouple reference junction drift is a routine repair on the recorders and loggers with TC/RTD inputs, restored for accurate temperature measurement.
My portable unit won’t hold a charge or won’t power on — can you fix it?
Yes. Battery degradation and power faults on the portable MR8870, MR8875, and MR8880 loggers are common and fully repairable.
Do you repair the wireless LR8410 logging system?
Yes. We service the LR8410 wireless system and its communication modules, along with the full LR8431 / LR8432 / LR8450 logger range.
What if my exact model isn’t listed?
We service every Hioki memory recorder and data logger configuration. If your model isn’t in the table, pick the closest match or email us — the process is the same.
Who uses Hioki memory recorders and data loggers?
Automotive test engineers, power electronics developers, mechanical and thermal analysts, building performance monitors, industrial process control teams, and environmental researchers rely on Hioki for transient capture and long-term monitoring.
