pH - Conductivity - Dissolved Oxygen - Temperature

Product catalog summary

Technical Specifications:
The HD 98569 is a portable multi-parameter data logger designed for electrochemical measurements such as pH, conductivity, dissolved oxygen, and temperature. It features a large back-lighted LCD display and is equipped with SICRAM modules for enhanced functionality.

Measured Values:
The device measures pH, mV, redox potential (ORP), conductivity, resistivity, total dissolved solids (TDS), salinity, dissolved oxygen concentration (mg/l), saturation index (%), and temperature (°C, °F).

Instrument Characteristics:
Dimensions are 250x100x50mm, weight is 640g with batteries, and it is made of ABS and rubber. The display is a graphic, back-lighted LCD with 128x64 points. It operates in temperatures from -5 to 50°C and humidity from 0 to 90% RH, with IP66 protection. Power options include 4 AA batteries or 12Vdc/1A mains.

Data Storage and Transfer:
The device offers unlimited data security, a real-time clock with 1min/month accuracy, continuous storage for 9000 samples, and command storage for 200 samples. Data can be transferred via RS232C or USB, with optional Bluetooth.

Calibration and Measurement:
pH calibration ranges from 1 to 5 points with 8 buffer options. Conductivity calibration can be automatic or manual with standard solutions. Dissolved oxygen calibration includes a quick calibration feature for long-term accuracy. Temperature compensation is automatic or manual.

Interfaces and Connectivity:
Includes RS232C and USB interfaces, with optional Bluetooth. Complies with EMC standards EN61000-4-2, EN61010-1, IEC1000-4-3.

Measurement Ranges and Accuracy:
pH range is -9.999 to +19.999 with an accuracy of ±0.001pH. Conductivity accuracy is ±0.5% depending on cell constant. Dissolved oxygen range is 0.00 to 90.00mg/l with an accuracy of ±0.03mg/l. Temperature range is -50 to +150°C with an accuracy of ±0.1°C.

Accessories and Ordering Information:
Includes data logger, batteries, calibrator, manual, software, and carrying case. Probes and solutions are ordered separately. Optional accessories include a Bluetooth module, USB/Bluetooth converter, and thermal printer.

Calibration Solutions:
Standard calibration solutions for conductivity measurements are provided at concentrations of 147µS/cm, 1413µS/cm, 12880µS/cm, and 111800µS/cm to ensure accurate calibration.

Oxygen Probe Calibration:
The quick calibration function for dissolved oxygen probes maintains measurement accuracy over time. Probes for pH, conductivity, dissolved oxygen, and temperature with SICRAM modules store factory calibration data.

Data Logging and Transfer:
The HD 98569 datalogger can store up to 200 individual screens and 9000 continuous samples. Data can be transferred to a PC via RS232C or USB ports, or wirelessly using Bluetooth with the HD22BT option.

Software:
DeltaLog11 software (version 2.0 and later) is used to manage and configure the instrument and process data on a PC.

Probes and Accessories:
Details various probes and accessories, including combined dissolved oxygen/temperature probes with replaceable membranes and Pt100 temperature probes for different measurement types.

Company Information:
Delta Ohm srl manufactures portable and bench-top instruments for various measurements including temperature, humidity, and pressure. They are located in Italy and comply with RoHS 2002/95/EC standards.
