HOBO Water Temperature Pro v2 Data Logger

$ 159.00 USD

The HOBO Water Temp Pro v2 is durable with 12-bit resolution. Complete with a precision sensor for ±0.2°C accuracy, this logger measures temperatures between -40°C and 70°C (-40°F to 158°F) in air and up to 50°C (122°F) in water. Its waterproof, streamlined case allows for extended deployment in fresh or salt water. Moreover, the Water Temp Pro v2’s optical USB interface makes it possible to offload data even while the logger is wet or underwater. A solar radiation shield is required to obtain accurate air temperature measurements in sunlight (RS1 Solar Radiation Shield, assembly required; or M-RSA pre-assembled Solar Radiation Shield).

2-Sensor Adapter for MX800 Data Loggers

This Adapter Lets You Monitor Multiple Parameters by Connecting Any Two Sensors—DO, CT, and/or CTD—to a Single HOBO MX800 Water Quality Data Logger.

This adapter supports the connection of any two sensors to one MX800 data logger- Dissolved Oxygen (part # W-DO), Conductivity Sensor (part # W-CT), and CTD sensor (part # W-CTD-xx).

Sensors can be attached directly to the fully submersible MX801 model, or to the end of a W-series cable that's connected to the direct-read MX802 model. Two sensors of the same type can be attached to monitor at multiple depths. When using a DO with CT or CTD combination, salinity-adjusted DO readings are logged directly without a need to perform post-processing.

The 2-sensor adapter comes with a sensor guard that screws onto the adapter to prevent damage to sensors while allowing ample water flow. Users also have an option to purchase an additional anti-biofouling guard (W-GUARD-2), which extends time between sensor cleanings by reducing fouling of the sensor.

• Can connect sensors directly (MX801), or cables to sensors (MX802).
• Protective housing screws on and off for easy access to sensors

Onset CTD Sensor for MX800 Series

A Conductivity/Temperature/Depth sensor for use with HOBO MX800 Series Water Loggers with sensor options available for 13, 30, 100 or 250 feet in a wide range of underwater environments; for use in freshwater or saltwater.

The CTD sensor is an interchangeable sensor that works with HOBO MX800 Series Water Loggers to measure conductivity, temperature, and water level. With this sensor attached to a HOBO MX800 Series Water Logger, the logger can also calculate specific conductance, salinity, and total dissolved solids (TDS). The CTD sensor can be attached directly to the fully submersible MX801 model, or attached via cable to the direct read MX802 model, which doesn’t require having to pull the sensor out of the water to download data.

Features

• 4-electrode conductivity sensor provides wide measurement range for monitoring freshwater or saltwater
• Conductivity sensor is centrally located to minimize effects from stilling wells or protective guards
• Durable ceramic water level sensor, located in the sensor tip for accurate measurement of shallow water levels
• Get water level directly with the MX802, no need for post-processing
• 1” diameter for use in narrow wells (with cable to MX802 above the well)
