Product Overview
Thermo Eberline Long-Reach Telescopic Geiger Counter Probe with Installed GM Tubes
Used, untested: no functional or radiological evaluation performed. Telescopic probe assembly with installed ZP1201 and ZP1301 Geiger-Müller tubes only; monitor, cables, and accessories not included. Originally designed for Thermo Eberline E600 portable radiation monitors; verify compatibility for your application. Cleaned and shows light signs of handling from prior use. Typically ships same business day from Idaho warehouse. Delivery to lower 48 states usually 3–5 business days.
Thermo Eberline long-reach telescopic Geiger counter probe engineered as an extension accessory for E600-series portable radiation monitoring systems. The probe integrates two specific Geiger-Müller detectors, a ZP1201 at the probe tip and a ZP1301 mounted below, forming a complete detector assembly rather than an empty mechanical extension.
Product Condition
Used and untested. The probe is clean and in excellent cosmetic condition with no visible structural damage to the telescoping sections. Installed GM tubes are present but have not been evaluated for output, calibration, or remaining service life.
Product Overview
Thermo Eberline equipment has long supported nuclear, industrial hygiene, and environmental monitoring programs where durability and continuity mattered more than rapid platform turnover. This telescopic probe reflects that approach, combining mechanical reach with a specific detector pairing intended for the E600 system. The presence of the original ZP1201 and ZP1301 tubes preserves detector geometry and reduces the need to source increasingly scarce legacy components.

Frequently Asked Questions
Has this probe been tested?
No. The probe and installed GM tubes have not been functionally tested or calibrated. It is offered untested.
What makes this probe different from empty extension probes?
This unit includes installed ZP1201 and ZP1301 Geiger-Müller tubes. These are specific detector models historically used with Thermo Eberline systems, making this a complete sensing assembly rather than a mechanical extension requiring retubing.
What is included with this listing?
The telescopic probe assembly with installed GM tubes only. No monitor, cables, documentation, or accessories are included.
Is it compatible with monitors other than the E600?
It was originally designed for the Thermo Eberline E600. Compatibility with other monitors or custom electronics is not verified and should be confirmed by the buyer.
Does cosmetic condition indicate detector performance?
No. Cosmetic condition reflects physical appearance only and does not indicate tube sensitivity, remaining life, or calibration status.
With its original ZP1201 and ZP1301 tubes still installed, this probe preserves the detector intent of the system it was built for, extending both physical reach and the service life of legacy radiation instrumentation.
