For over a month this ORP meter has worked like a champ. " when turned on again. After disassembling, I found moisture in the compartment where the module is plugged into the flash drive. Blow it out, let it dry for several hours and put the device back into self-test mode. Today the The device could didn't do a self test and after calling FLIR a technician walked me through a "soft reset" which didn't fix the problem I was then put through to CSR who asked for my bill and said a new unit would be sent me as soon as possible Service was excellent I received the new item on time Looks like the device is really not well designed to replace the ORP module with a pH module on a regular basis and maintain a waterproof status I recommend , to ensure this upon receipt The block assembly is sealed and if you need a pH meter, buy a separate product, I will only use this device for P Check the ORP and do not immerse further than the module lock nut.
