This range of table mountable type vacuum leak testers is useful apparatus to determine system error caused by leakage of vacuum. These testing apparatus are used for handling outdoor electrical housings, vacuum source based machine components and underwater sensor. Developed as per international norms, this range of vacuum leak testers deserves praise for its microprocessor based high precision operation, mechanical sample testing arrangement and calibration facility. Units or parameters of their timer can be changed as per testing requirements. For simplifying pressure monitoring process, these systems have digital pressure display arrangement. These stainless steel/mild steel apparatus come with powder coated structure for their prolonged service life.
