The ARS AV-Fill Thermometer is designed to monitor the temperature of the water used to fill the Artificial Vagina. It attaches to any faucet with a standard 3/4" garden hose thread. A faucet adapter (not included) may be required to fit the AV-Fill Thermometer to other faucet thread configurations. The thermometer has a 2" diameter dial which indicates 0°-100°C and is marked with color bands for easy identification of important temperature ranges. Included is 4 feet of clear plastic tubing to allow quick and easy filling of the AV once the faucet water has reached the appropriate temperature. Instructions for use and calibration are included.
