Solusi Data Logger di Indonesia
Perekam data nirkabel multiparameter Seri HOBO MX800 bekerja dengan sensor yang dapat diganti untuk memberikan solusi yang sangat dapat dikonfigurasi untuk memantau konduktivitas/salinitas air, suhu, kedalaman, dan oksigen terlarut (segera hadir). Tersedia dalam model yang mudah digunakan dan dapat ditenggelamkan sepenuhnya (MX801) dan model baca langsung (MX802) untuk kemudahan pemindahan data yang tidak perlu melepas sensor dari air.

| Wetted Materials | Logger: PVC housing with polyester film label, PET sensor connector end cap and mounting handle with EPDM and Buna-N O-rings, passivated 316 stainless steel hardware rated for use in saltwater; MX802 also has ePTFE vent |
| Collar: HDPE, titanium screws | |
| Note: logger should be mounted so that no metal parts of the logger are in contact with other metals | |
| Depth/Environmental Rating | MX801: IP68; waterproof to 100m (with sensor(s) attached) |
| MX802: IP67, NEMA 6; Weatherproof (with cable or Termination Plug attached); this model is not waterproof | |
| * Pressure Accuracy: Absolute pressure sensor accuracy includes all sensor drift, temperature, and hysteresis-induced errors. | |
| *** Changes in Temperature: Allow 20 minutes in water to achieve full temperature compensation of the pressure sensor. There can be up to 0.5% of additional error due to rapid temperature changes. | |
| ***Water Level Accuracy: With accurate reference water level measurement, known water density, and a stable temperature environment. System Water Level Accuracy equals the sum of the Barometric Water Level Accuracy plus the selected CTD sensor Water Level Accuracy. | |
