Water Level Data Logger Starter Kit (30’)- HOBO - KIT-S-U20-01

Feature

• Perlindungan petir - tidak ada kabel sinyal yang panjang, dan elektronik terlindung di perumahan stainless steel (lihat gambar lokasi sensor logger Water Level)
• Perangkat lunak HOBOware Pro memberikan konversi mudah ke pembacaan tingkat air yang akurat, kompensasi penuh untuk tekanan barometer (lihat demo), dan kepadatan air.
• Multiple-rate sampling (lihat demo) memungkinkan pengambilan sampel lebih cepat pada saat-saat kritis seperti saat memompa dimulai atau berhenti.
• Tersedia dalam 4 rentang kedalaman
• Ideal untuk digunakan di sumur, sungai, danau, lahan basah dan daerah pasang surut
• Desain no-vent-tube untuk penyebaran yang mudah dipercaya
• Sensor tekanan keramik tahan lama

Pressure Sensor
Operation range: 0 to 145 kPa (0 to 21 psia); approximately 0 to 4 m (0 to 13 ft) of water depth at sea level, or 0 to 7 m (0 to 23 ft) of water at 3,000 m (10,000 ft) of altitude
Factory calibrated range: 69 to 145 kPa (10 to 21 psia), 0° to 40°C (32° to 104°F)
Burst pressure: 310 kPa (45 psia) or 18 m (60 ft) depth
Water level accuracy:* Typical error - 0.075% FS, 0.3 cm (0.01 ft) water
Maximum error: - 0.15% FS, 0.6 cm (0.02 ft) water
Raw pressure accuracy:** 0.3% FS, 0.43 kPa (0.063 psi) maximum error
Resolution: < 0.014 kPa (0.002 psi), 0.14 cm (0.005 ft) water
Pressure response time 90%: < 1 second
Thermal response time (90%): † Approximately 10 minutes in water to achieve full temperature compensation of the pressure sensor

Response time (90%): 3.5 minutes in water (typical)
Stability (drift): 0.1°C (0.18°F) per year

Logger
Real-time clock: ± 1 minute per month 0° to 50°C (32° to 122°F)
Battery: 2/3 AA, 3.6 Volt Lithium, factory-replaceable
Battery life (typical use): 5 years with 1 minute or greater logging interval
Memory (non-volatile): 64K bytes memory (approx. 21,700 pressure and temperature samples)
Dimensions: 2.46 cm (0.97 inches) diameter, 15 cm (5.9 inches) length; mounting hole 6.3 mm (0.25 inches) diameter
Weight: Approximately 210 g (7.4 oz)
Wetted materials: 316 stainless steel, Viton® o-rings, acetyl cap, ceramic sensor
Shock/drop: Logger is sensitive to shocks. Handle with care and avoid any impact. Always use proper packaging when shipping the logger.
