Diversitech Airflow Measurement

Overview

The DIVERSITECH CT-SRH77A is a superheat and wet bulb diagnostic kit designed for HVAC technicians performing refrigerant system analysis and airside performance checks. The kit includes a digital temperature and humidity meter with a backlit display and sealed keypad, a stainless steel puncture probe, an aluminum pipe strap surface probe, and a dedicated humidity probe. The meter measures temperatures from 40 degrees F to 300 degrees F and relative humidity from approximately 10% to 95%. Built-in wet bulb calculation and temperature differential measurement make it a capable tool for evaluating system performance without additional instruments. This kit is suited for residential and light commercial HVAC service work where accurate superheat and wet bulb readings are required during system commissioning, refrigerant charging, and diagnostic calls. The multi-zone monitoring capability allows a technician to track conditions across several measurement points in a single session. The sealed keypad resists moisture and debris common in field service environments. The combination of three probe types in one kit covers suction line surface readings, refrigerant line puncture access, and ambient humidity measurement in a single package. Key Features Temperature range: 40 degrees F to 300 degrees F for broad system coverage Relative humidity measurement from approximately 10% to 95% Built-in wet bulb calculation eliminates manual psychrometric chart lookup Temperature differential…
