Description

The dipperLog NANO is a low-cost, accurate groundwater level logger. It is used by homeowners, hydrogeologists and other groundwater professionals who require a durable, reliable and cost-effective solution for long-term monitoring of groundwater levels and temperature in wells, piezometers, boreholes and surface waters . The Heron logger is also ideal for short-term pumping tests and slug tests, or for wetland and tidal studies.

With intuitive, easy-to-use software, the dipperLog NANO is simple to start up and data retrieval is quick and easy.

The Heron Instruments dipperLog NANO system allows users to enhance their data logging projects with a family of compatible, affordable accessories.

PC communication cable - PN # 5009 + Software - PN # 5008

The PC communication cable is required to set up, download and reprogram the dipperLog NANO to a PC. The software is included or can be downloaded from our website. One PC communication cable is required for each PC user.

barLog NANO – PN# 5116

A barometric logger is used to automatically compensate the readings stored in the dipperLog NANO for changes in barometric pressure (for non-vented versions). The barLog NANO is recommended for barometric compensation, for long-term monitoring or where more than one logger is deployed within a 20 km radius

tapNtell Surface-Mount Display – PN # 5020

The tapNtell is a weatherproof display for the dipperLog NANO. The tapered connector end of the tapNtell connects to the direct-read well head, and the surface-mount display unit can be attached to the side of the well cover or pumping station (any solid surface). The tapNtell provides an instant, real-time reading of water level and temperature at the touch of a finger.

showNtell Hand Held Display – PN# 5018

The showNtell is a portable hand held display unit for the dipperLog well head readout version. The showNtell can be carried from well to well, to give an instant real time reading of water level and temperature by simply plugging into the direct read well head. The showNtell does not download or store the data from the logger.

SDI-12 Interface Cable – PN# 5021

The SDI-12 system allows dipperLog NANO data to be accessed from remote locations by a central computer without site visits. Sensors can be swapped without reprogramming the data logger with calibration or other information. Power is supplied to the sensors through a third-party device that allows telemetric data reading.
Operating voltage (DC) :: 7.5 – 35 VDC
Supply current (standby) :: 10μA
Supply current (active) :: 1.5mA

Locking caps for piezometers – PN# 5007

The nylon well cap is airtight and has a tamper-proof hinge, ideal for deploying the dipperLog NANO in a piezometer.

Plug – PN# 5006

The nylon expansion cap is an airtight sealing plug, ideal for deploying the suspended version of the dipperLog NANO in a piezometer.
