1 GEIGER-MULLER TUBE - PSU BASE - NEW! A new, approved Geiger- Muller (GM) tube, for the detection of radiation, from alpha, beta and gamma radiation sources, and for radiation leak testing. The GM tube is mounted in a robust case with removeable front protective grill and removeable rod to allow clamping in a retort clamp etc. if required. This LND7224 GM tube is the same specification, and equivalent to, the ZP1481 type. Supplied complete with 2 metre coaxial cable and BNC to TNC adapter, to allow use with scaler-timers or ratemeters with either BNC or TNC connectors. Cat No. Description Price Per RAD-320-100 Geiger-Muller Tube - PSU Base 461.55 ea. 2 GEIGER-MULLER TUBE- 3B A GM tube from 3B Scientific, with a self- quenching halogen pulse ionisation chamber, for detecting alpha, beta, gamma and x-ray radiation. The GM detector is mounted within a metal housing, with mica window, and a removable mounting clamp with shaft. Operating voltage: 400 - 600V (recommended: 500V). The GM tube holder comes with a BNC fitting, but is supplied WITHOUT a BNC lead, which is available separately (RAD-350-150). Size: Shaft - 100mm x 10mm diameter; Window 9mm diameter; Tube - 85mm x 25mm diameter. Designed for use with a 3B Scientific scaler timer. Cat No. Description Price Per RAD-350-100 Geiger-Muller Tube 295.51 ea. RAD-350-150 GM Tube Connecting Lead BNC-BNC 23.73 ea. RAD-350-200 BNC to TNC Lead 27.79 ea. 3 GEIGER-MULLER TUBE ZP1481 - IPC This GM Tube & Holder is housed in a robust casing and has been designed to work directly with scaler -timers and ratemeters which have either BNC or TNC connectors. The GM Tube contained within the holder is the industry standard type, ZP1481, which has a sensitive, large area detection window and can be used for detecting alpha, beta and gamma radiation. The mica window has an overall diameter of 24 mm, with a ‘useful’ diameter of 17 mm. The holder provides protection to the GM Tube and includes a fixing rod to allow mounting in a squat base (STR-430-100) or retort clamp. Also contained within the Holder is a high value (4.7 MOhm) series resistor. The detection window has a protective grill covering, which can be removed for detecting low levels of radiation or for performing comparative radiation tests using a test source. The holder also includes an attached lead fitted with either a BNC or a TNC connector, for attachment to a scaler-timer, counter or ratemeter (the TNC version is compatible with the IPC Scaler timer, TMH-760-100). Please note: As with all GM tubes, the detection window is VERY fragile so the GM tube should be handled carefully. If the window becomes damaged, a GM tube will cease to work and is not repairable. Cat No. Description Price Per RAD-340-100 GM Tube ZP1481 With BNC 480.40 ea. RAD-340-150 GM Tube ZP1481 With TNC 480.40 ea. 4 LOGIT RADIOACTIVITY SENSOR For measuring Alpha, Beta and Gamma emissions. Ideal for measuring half life and radioactive decay. Can also be used as a background radiation counter & general radiation detector. Suitable for use with LogIT dataloggers Suitable for use with LogIT dataloggers - see DATALOGGING pages Cat No. Description Price Per DAT-400-300 Radioactivity Sensor 352.00 ea.
