Description

The AP-LITE Package features the single parameter probe in a rugged carry case with the GPS-Aquameter Display, AP-LITE probe, 3m extension cable and other accessories. The only missing bit is the Optical Electrode for the parameter you want to monitor. The AP-LITE package allows users to connect directly to the LITE Optical Electrode for a water quality monitoring system to monitor a single parameter. The connected Electrode can be swapped to take different readings in the same water source to cover any of the available parameter. This package is perfect for fieldwork where real-time data viewing, logging, and GPS tagging are essential, making it an ideal choice for efficient, modern water quality assessment across various applications.

Features

  • Handheld Display: Connects with the GPS-Aquameter Display, supplied.
  • Real-time Data Viewing: See measurements instantly on your mobile device.
  • Data Logging & Export: Record and store measurement data, easily exportable for analysis.
  • GPS Tagging: Automatically logs the geographic location of each measurement.
  • Single Parameter Focus: Retains the simplicity and cost-effectiveness of measuring one specific water quality parameter.
  • Compact & Portable: Maintains the lightweight and robust design for field use.

Applications

  • Field Surveys & Mapping: Rapidly collect and map water quality data with GPS locations across a site.
  • Remote Monitoring Spot Checks: Ideal for checking specific points in widespread monitoring networks.
  • Citizen Science Initiatives: Empowering community groups to collect geo-referenced water quality data.
  • Environmental Impact Assessments: Documenting precise measurement locations for environmental reports.
  • Academic Research: Efficient data collection for studies requiring location-specific parameter measurements.
  • Regulatory Compliance with Location Data: Providing verifiable location information for compliance reporting.
  • Tracking Pollutant Plumes: Monitoring a single parameter (e.g., turbidity) with location data to trace movement.

The AP-LITE is a simple probe with a single optical socket and an integrated temperature sensor. This socket is able to house any one of the optical electrodes in the table below, links to get more details on the parameter for each probe.

Fluorescence measurement techniques are not ideal for quantitative measurement and it is therefore impossible to specify an absolute accuracy. The accuracy figures quoted above represent the equipment’s capability at the calibration points at 25°C. In order to obtain accurate results, data obtained with a fluorescent electrode in the field must be post-calibrated with data from standard laboratory analysis of grab samples acquired during the study.

To fit an Electrode, first remove the sleeve from the AP-Lite by unscrewing at the blue split-line. Apply a small amount of silicone grease (supplied with the AP-Lite) to the threaded section and the O-ring of the AUX Electrode (see photograph). ENSURE NO GREASE IS APPLIED TO THE GOLD CONTACTS. Use a clean cloth or tissue paper, polish the gold contacts ensuring they are completely clean. Carefully insert the electrode into the socket and tighten firmly by hand until the O’ring is completely compressed. Do not over-tighten or use any tool (such as pliers). After fitting the Electrode, replace the Sleeve and ensure the Sleeve End Cap is fitted.

Once a new electrode is fitted it is essential to carry out a full two-point calibration prior to use. Calibration solutions are available with the relevant optical electrode. The carry case has space to hold suitable calibration solutions
