The TSI HM675 and HM685 manometers are used to balance hydronic heating and cooling systems, check pump performance and to set balancing valves. Both models can calculate flow using valve manufacturers Cv (Kv) factors (up to 100 Cv (Kv) can be entered). They can also 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. They have a robust, splash-proof case ideal for transporting to and from site.
Features
- Measure and display high side, low side and differential pressure simultaneously from 0 to 2,068 kPa (300 psi)
- Robust, splash-proof case
- Inputs for two temperature probes
- Calculates flow using valve manufacturers Cv (Kv) factors (up to 100 Cv (Kv) can be entered)
- Stores up to 4000 data points to memory for later recall/download to a PC using CompuDat USB Software and USB interface cable
- Intuitive menu structure for easy navigation and instrument set up
