TENMARS ELECTRONICS TM-91N Radiation Monitor electrician tool

Radiation monitor for beta.

The TENMARS TM-91N is a handheld radiation monitor designed to measure Beta, Gamma and X-ray radiation levels. It displays readings in microsieverts per hour and microrems per hour using a built-in Geiger-Müller tube. The instrument provides automatic ranging and detection, while an audible beeper signals each count and an audio alarm can be set for threshold warnings. It is suited to environmental safety checks, industrial surveys and border inspections.

Suited to professionals needing portable radiation

This monitor fits users who require a compact, battery-operated survey meter for routine area monitoring or spot checks in nuclear, medical, mining or metal-working environments. It is not intended for buyers who need alpha-particle detection or laboratory-grade spectroscopy. Users who require data-logging, computer connectivity or isotopic identification should consider instruments that provide those capabilities.

Verify power source and regulatory requirements

Confirm the battery type and availability for the TM-91N so the unit can be operated immediately on receipt. Check whether local regulations require calibration certificates or specific licences for radiation measurement equipment in your intended application. Ensure the measurement ranges and alarm functions match the safety thresholds used in your workplace or inspection protocol.
