Digital Manometer for Surface Pressure Difference and Wind Pressure HT636

HT636 Digital Manometer for Surface Pressure Difference and Wind Pressure delivers precise differential pressure readings with a ±5 PSI measuring range and a rapid 0.5-second response, making it ideal for HVAC work and industrial differential pressure checks. It measures surface pressure differences and wind pressure with a compact, portable design you can take on-site, while providing clear readings on an ICD display and supporting multiple pressure units for versatility.

Designed for reliability in real-world environments, the HT636 supports differential pressure gauge metering with easy operation and a user-friendly interface. It can withstand up to 10 PSI and offers precise results with an accuracy of ±0.3% FS, repeatability of ±0.2% (max +0.5% FS), and a linear/posterior of ±0.29% FS. The instrument can display maximum, minimum, and average values and includes an under-voltage prompt for safeguarding readings.

All electronic and mechanical equipment sold by InterCyprus to EU countries is CE certified and carries a two year warranty.

Benefits & Tips

• Use for HVAC ductwork testing, filter performance checks, and industrial differential pressure monitoring.
• Rely on the 0.5s response time for quick diagnostics and the ability to log max/min/avg readings for trend analysis.
• Keep readings stable by using the ZERO reset after connecting hoses and using the auto-shutdown feature to preserve battery life.
