The new SCM3 Carbon Monoxide (CO) Detector is a standalone instrument that measures CO in parts per million (ppm). Its electrochemical sensor is fast enough for walk-around tests.

Features and benefits include:

• Fast electrochemical sensor measures 0 to 1000 ppm CO (2000 ppm CO with 5 min maximum exposure time)
• Calibrate/Zero SCM3 to ambient quickly (when CO levels are below 5ppm) with the ZERO button.
• Audio and visual alarms w/ mute.
• Bright-blue, backlit dual-display with MAX and real-time measurements displayed.
• Magnetic hanger for hands-free operation.
• Auto Power-Off (APO) to extend battery life.
• Check approximate % of battery life remaining by holding MUTE for 2 seconds.
• Runs on a standard 9V battery (included).
• Use option pump (AOXP2) for remote / flue gas testing (see SOX2 below).

The new SOX2 Combustion Check meter that measures percent oxygen (%O2) and flue temperature and calculates percent carbon monoxide (%CO2) and percent excess air (%EA).

The SOX2 is an affordable alternative to full-function combustion analyzers. It's designed for techs who want to do everyday combustion testing and tuning, without paying for all of the costly extras found on combsution analyzers - extras they don't need or care about.

The SOX2 allows you to easily calibrate combustion equipment such as boilers or furnaces to the manufacturer’s specified Excess Air %, CO2%, or O2%. Tuning the Excess Air, CO2, O2 stack temperature and temperature rise to match the appliance manufacturer’s specifications will increase efficiency and help maximize performance and life expectancy of the equipment. Tuning typically involves adjusting the air/fuel ratio.

Description and Application

The SRH2 is a complete digital psychrometer and a very valuable HVAC diagnostic tool. As a psychrometer, it measures wet bulb (WB), dry bulb (DB), percent relative humidity (RH%), and dew point (DP). As a diagnostic tool, it helps the HVAC technician easily diagnose problems with air flow across the evaporator. It can also calculate the target superheat of a fixed restrictor air conditioning system.

Use the NORM mode (normal psychrometer) to display wet bulb (WB), dry bulb (DB), percent relative humidity (RH%), or dew point (DP).

Use TSH (Target Superheat) to help set the proper refrigerant charge for a fixed restrictor system.

Use the Fieldpiece SSX34, ASX14, or ASH3 to easily measure Actual Superheat without the need of additional charts.

Use TEET (Target Evaporator Exit Temperature).

Includes 2 K-type thermocouples with alligator clips- wet bulb and dry bulb.
