The Apex Instruments Standard Method 5 Heated Probe Sheath feature 1" diameter sheaths constructed from corrosion resistant stainless steel, modular 3/8" pitot tip, 1/4" stainless steel quick connects, Type-K thermocouples for stack & probe temperature, probe heater and an orsat line, small parts package. Standard lengths are 3’ to 16’. Longer lengths and custom orders are available by request. Order probe liners separately. Probes are ordered according to nominal (liner length). Effective length is one foot less than nominal length.

Method 5 Probe (Tube) Heaters
Features a tightly wound heating element around a rigid tube. The rigid tube design allows liner replacement without removing the heating element. Actual tube length is 2-3/8" less than nominal length. Apex probe heaters are designed to operate at the method 5 specified temperature of 245°F (+/-25 Degree F). Specify alternate temp requirement if needed at the time of order. The maximum recommended temperature is 260°C (500°F). In extreme applications (probe heaters over 11 feet, long u-cord, long power extension cord), power drops may occur. In these instances, a separate temperature controller is suggested. See Gas Analysis Section, Page 9 for Apex ICH-901 Temperature Controller. Alternate wattage requirement to be specified at time of order.

Replacement Pitot Tips
The unique design of the Apex Modular Pitot Tip reduces the collection of water droplets in the pitot lines. The lower tube is self-draining while the offset in the upper tube acts as water trap. ‘S’ type pitots manufactured in accordance with U.S. EPA Reference Method 2 may be assigned a baseline coefficient of 0.84. Geometric and wind-tunnel calibrations are offered.

Optional Packing Gland
2" Oversheath Packing Gland, 2" NPT Threads, Stainless Steel with PTFE Ferrule. Must be Specified at time of order.
