The HM675 and HM685 Hydronic Manometers are used to balance hydronic heating and cooling systems, check pump performance and to set balancing valves. They can measure and display differential, high side and low side pressure simultaneously, without having to change hose connections or instrument valve settings. Each model features a backlit display and operates on four alkaline or NiMH rechargeable batteries.

We are offering Micro Manometer to our clients.These robust instruments can be used with pitot probes to measure duct velocity.

The on-line gloves Integrity Tester GT-2.0 produced by Beijing Neuronbc Laboratories is designed according to the positive pressure leak detector principle proposed by GB/T 25915.7-2010/ISO 14644-7:2004, and it is a dedicated instrument to detect the gloves leakage. The simple and easy design won't need any additional equipment, no need to remove the gloves, with fast detection speed and high precision.

Features

• The instrument adopts a small amount of frequent air inlet mode, with uniform inlet velocity in gloves, to avoid gloves deformation.
• It is equipped with color touch screen and humanized interface design, according to different test parameters, for automatic selection and matching, which can be most adaptive to the current gloves test procedure, date and time display;
• The authority management and electronic signature design is in line with the 21 CFR part 11 for certification requirements of electronic records and electronic signature;
• It is convenient to move, easy to carry and quick to connect;
• Historical records can be used for print, storage and query.
