FAQ

What can the SevenGo Duo™ portable meter be used for?

The SevenGo Duo™ is a dual-channel portable meter offering data memory and data transfer capabilities for measurement of pH, conductivity, ion concentration, ORP and dissolved oxygen. The kit versions of this instrument are well suited for outdoor use or use in-line. Both the meters and the sensors are robust and watertight (IP67).

Description:

  • The SevenGo Duo™ has five-point pH calibration with a choice of seven pre-defined and one user-defined buffer set
  • Data storage for 500 GLP data records with time/date, sensor ID and SN, as well as user and sample IDs
  • Contact-free IR communication
  • Intelligent Sensor Managment (ISM®)

Seven Good Reasons for the SevenGo Duo™:   

  • Easy and intuitive operation
  • High measurement accuracy
  • Large, easy-to-read display screen
  • Ergonomically designed, watertight and robust
  • Comprehensive range of practical accessories
  • Modern GLP data management
  • Revolutionary Intelligent Sensor Management (ISM®)

How can data be transferred from SevenGo Duo™ to a PC with infrared?

Infrared data transmission is not state of the art anymore. Therefore, there are no longer many programmers who are developing controllers for this technology.
We successfully tested the following combination to transfer data from SG78 to a PC: use the IR-RS232 adapter (P/N 51302333) in combination with the RS232-USB adapter (P/N 64088427). The IR-RS232 adapter needs a 9V power supply to work.The recent PC software EasyDirect™ pH is not designed to support SevenGo™ meters. Instead the last version of LabX Direct™ pH, version 3.4, shall be used. The baudrate in that software must be set to 1200 (not 9600).

Do SevenGo Duo™ meters meet IP67 when no sensor is connected and the meter is on?

SevenGo Duo™ meets the requirements of IP67. This applies to the entire measurement system as well as to the meters themselves.

What is the different between an ISM® light and normal version on the SevenGo Duo™?

Differences between ISM light and "normal" ISM:

  • only the recent calibration data can be reviewed
  • neither sensor name nor the serial number can be reviewed
  • no additional information like maximum temperature can be reviewed
  • a calibration is saved without date/time or user name

ISM® light is used for mid-level instruments with segmented display and without date/time, user ID and similar information: SG23, S2, S3, S4. In other words: the difference between ISM® light and "normal" ISM® with the SevenGo Duo™ instruments is the same as between ISM® of SG23 (SevenGo Duo™) and of SG78 (SevenGo Duo Pro™).
