Greetings All, We are selling Ludlum Model 43-37 Gas Flow Proportional Counter probes. These probes use P-10 gas and are frequently used with the Ludlum Model 239-1F floor monitor carts or for large area surveys by hand. We have the brackets for the floor monitor carts and even have carts for sale on our website (CHP Consultants). Some people attach handles and use the probes by hand to survey large areas such as walls, trucks, floors, etc. We have a limited number of the handles which we can sell for an additional $15 while they last. We have the smaller 43-68 probes too and hope to have them listed on our Ebay store and online. Note the gas connectors one each end and the "C" connector. We can change the C to a BNC if you want for about $15 more. We can calibrate these probes with NIST Traceable sources for an additional $40. If you want the accessories, let us know when you buy and we will bill you for them if they are available.
