Features: Pressure rating 0-10 bar. Temperature rating 0-120��C. Two standards available: 1/8 and 1/4 inch. Suitable for underfloor heating systems. During installation, please do not use hand to move the straight-line wire (pressure gauge movement, light, is on the same line). Pulling by hand (header rotation) can lead to uneven pressure gauge structure deformation and damage the internal structure. Use an external wrench instead. Package Includes: 1x Temperature Pressure Gauge Specifications: Material: plastic Thread: 1/8 or 1/4 inch (optional) Diameter of external thread: 9.5 �� 0.2 mm Diameter of internal thread: 8.8 �� 0.2 mm Pressure range: 0-10 bar Temperature range: 0-120 Installation Instructions for the home water distributor: 1. Locate the mounting hole of the water distributor and measure the size of the internal thread with calipers. 2. Determine if a thermometer can be installed, and then use a wrench to securely attach the thermometer to observe pressure and temperature. Note: Please allow 1-3 cm error due to manual measurement. Ensure you are okay with this before bidding. Due to differences in monitors, the picture may not reflect the actual color of the item.
