TD-Diver - New!
With its 22 mm diameter the TD-Diver water level logger is a totally new design which combines over 75 years of groundwater monitoring experience with the most recent technologies and components available in the market.
The TD-Diver is based on an ingenious and proven concept and is acknowledged as the most reliable instrument for the autonomous measuring and recording of groundwater level and temperature. Its internal working memory of 72,000 measurements per parameter provides sufficient capacity to perform one measurement every 15 minutes for over 2 years. For each measurement, the Diver registers the date and time, groundwater level, and temperature.
Overview
The TD-Diver provides reliable automatic measurement and registration of groundwater level and temperature data
Advantages of the Mini-Diver
- Broad measuring frequency range: 0.5 sec - 99 hr
- Storing up to 72 000 measurements
- Continuous or fixed length memory (progammable)
- Backup memory for data security
- Small size (ø22 mm x 110 mm)
- Simpler deployment due to its increased weight (104 g)
- Ceramic sensor
- Extremely long battery lifetime
- Logger and battery in one hermetically sealed housing
- Possibility of installation without the optional data cable, thus:
- cheaper installation
- much easier installation in small diameter wells
- virtually damage proof
To install the TD-Diver in a monitoring well you will only need the TD-Diver and a 1 mm diameter stainless steel cable. Obviously, the TD-Diver may also be installed using a data cable!
