The Ultimate Reliable & Trusted Liquid Manometers

Why so many companies are now using TSI manometers

• Wide 2068 kPa pressure range so they can be used for all sorts of HVAC applications including heating and cooling systems, pumps, chillers, fan coils and much more. Don’t limit yourself by buying instruments that only cover a limited pressure range.
• They do it all in the one instrument. No need to bolt on extra adapters and parts. The HM600 series are ready to start taking measurements immediately
• They can be easily used with every brand, make and model of valve on the market. Simply enter your flow curve for Stadt valves and off you go
• Sick of paying too much for overpriced meters which give you grief and break down? Sick of buying cheaper meters to save money which break down even faster and also under perform? The HM600 series are the most reliable, stable and proven meters we have come across to date, as reported by client after client for many years.
• They can quickly and reliably be zeroed unlike some competitive instruments
• They are easy to use, simply turn them on for trusted, reliable, repeatable results
• Simultaneously display differential, high side and low side pressures without having to change hose connections or instrument valve settings
• Easy to read backlit display. Operates on standard or rechargeable AA batteries
• Easily calculates flow using manufacturers Cv (Kv) factors (HM680 model)
• Calculates heat flow, impeller diameter, brake power and much more (HM680 model)
