Yet another “Bullet Proof” hand held meter made by Ludlum. Not some plastic housing meter that is just waiting to crack after the first drop. This general purpose, handheld analog ratemeter supports operating two separate radiation detectors. A switch allows the user to select between the internally mounted GM detector with an exposure range of 0–2000 mR/hr (0–20 mSv/h) or an external GM or scintillator detector of choice.
Add a Counts.Pro for $399 to digitize your surveys and turn your meter into a digital scaler/ratemeter/cloud connected GPS datalogger! Take your meter to the next level with Counts.Pro
The aluminum cast instrument housing, with its separate battery compartment and accompanying metal handle, offer an industrial robustness and quality that promote long-lasting protection and instrument life. The front-panel controls include a rotary switch for selecting the five-decade range and instrument shut-off, an audio on/off switch, a fast/slow response switch, a high voltage display button, and a battery test button.
The analog meter face comes in a variety of options to support the measurement units and ranges for the additional external detector selected. Call if you want a specific meter face.
This meter, like everything else we sell comes with our standard 30 day unconditional warrantee.
This is a USED METER. The Meter in the Photo is a STOCK PHOTO and is not likely to be the actual meter you will be getting. Ask and we will send you the serial number and photo of the actual meter. Some of these meters have scratches, but all of them are fully functional and will meet the original factory specifications for use.
Features:
Internal Detector
