Standard Features
- SDI-12 interface provides “plug and play” connection with compatible measuring devices – including multi-parameter sondes from leading manufacturers.
- Standard 512KB of memory gives you great flexibility for logging environmental data.
- Corrosion-proof refrigerator cabinet is molded from polyester resin fiberglass and UV-resistant gel coat provides a smooth, non-porous finish for added protection and easy cleaning
- Heavy-duty stainless steel frame and cabinet.
- Automatic built-in heater ensures that samples won’t freeze, even when ambient temperatures drop to -20°F (-29°C).
- Durable powder-coated epoxy, phenolic paint, or polyester tubing, protects refrigeration components.
- Sample delivery at the EPA-recommended velocity of 2 ft./sec., even at head heights of 26 feet.
- Pump revolution counter and patented liquid detection sensor ensure accurate sample volumes – and tells you when tubing should be replaced.
