Features
• Records highly accurate groundwater and surface water level and temperature measurements
• It combines a robust Hastelloy pressure sensor, temperature detector, 10-year lithium battery datalogger
• 22 mm x 160 mm stainless steel housing
• Baked-on coating using polymerization technology protects the body against corrosion, abrasion and high temperatures
• Hastelloy sensor has excellent performance in harsh environments and can withstand 2 times overpressure without permanent damage
• Readings are stable in extreme pressure and temperature conditions
• Hastelloy sensor can withstand 2 times over-pressure without permanent damage
• Single-eye optical for easy cleaning and more reliable, faster communication
• Memory for 150,000 sets of readings
• Stronger, more robust design: double O-ring seals for increased leakage protection
• Better thermistor sensitivity: upgraded platinum RTD
