SevenExcellence

Weatherproof Design

IP67 protects against dust and immersion in water in depths down to 1 m. This makes for a durable portable meter that is able to withstand harsh and demanding environments.

Rubber Holster

Included with every Seven2Go™ meter is a rubber holster that offers protection again drops, dirt, chemicals and UV light. If yours is lost or to be replaced, it can be purchased separately as well.

Drop Test

Working in the field increaes the risk of accidental drops. Seven2Go™ can withstand impact of a drop, adding extra value if you work in difficult environments.

 
SevenExcellence

Comfortable and Fast Navigation

Seven2Go’s new T-Pad improves the speed with which you move through menus. The smart button arrangement allows for faster navigation that provides you shorter time to actual measurement.

StatusLight™ Indicator
 

Thanks to the new StatusLight™ you are instantly aware of how the meter is doing. An easy to understand traffic light concept shows if your meter is ready or not.

Side-Guards for Extra Grip
 

Soft rubber side-guards allow the meter to be operated comfortably with one hand and reduce the risk of the meter slipping during measurement.

 
SevenExcellence

uGo™ Carrying Case

Provides ideal protection and propper fitting for any Seven2Go™ meter, sensor and all of the accessories needed to perform regular measurements outdoors.

Weatherproof USB

With the IP67 USB connector, data can be transferred to a PC anywhere and at all times, under any weather condition.

Sunlight Proof

Read your results or browse through the menu even under direct sunlight. The screen is designed so that it is not affected by sunlight and has enough backlight power to read even in dark areas.

FAQ

What can Seven2Go™ portable meter be used for?

Seven2Go™ - Single-channel portable instruments (IP67) engineered to provide users with fast and reliable pH, Conductivity, Dissolved Oxygen, Ion Concentration and ORP determination in the lab, at-line or outdoors.

Seven2Go™ Description:

  • New intuitive menu guarantees out-of-the-box operation for anyone
  • T-Pad provides comfort and improves the speed with which you move through menus
  • Automatically recognizes InLab ISM™ (Intelligent Sensor Management) sensor and stores sensor ID, serial number, and last calibration data, thereby reducing chances of error
  • IP67 protection and drop test resistance make these meters weatherproof (withstand harsh and demanding environments)
  • Supports 12 languages and offers a user interface that uses complete words and sentences
  • Lack of cryptic expressions simplify operation and reduces strain on the user
  • Sunlight-proof: direct sunlight enhances screen's contrast and guarantees an excellent readability even under bright and sunny conditions
  • StatusLight™, an easy to understand traffic light helps to check if your meter is ready or not
  • 1- to 5-Point calibration
  • Graphic LCD display
  • Ability to perform automatic, manual and time-dependent endpoint recording
  • Perform serial measurements in user-defined time interval
  • Acoustic and visual endpoint signal
  • Other features include: Time and date option, three user levels (Routine, Expert, Outdoor), Calibration reminder, Sensor ID, SN, Sample ID, User ID, User-defined alarm limits, PIN protection
  • Includes three predefined conductivity standards
  • User-defined conductivity standards
  • Manual cell constant entry
  • Automatic/Manual temperature compensation
  • Linear, non-linear and pure water temperature correction mode

What is the different between an ISM® light and normal version on the Seven2Go™?

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 Seven2Go™ instruments is the same as between ISM of S3 (Seven2Go™) and of S7 (Seven2Go Pro™).

 

Do USB Printers comply with the Seven2Go™ portable meter?

Data can be transferred from the Seven2Go Pro™ to a PC for printing. Currently the Seven2Go™ cannot be used directly with a compact printer.

What electrode clip is used with the Seven2Go™?

For Seven2Go™ meters you get two of these electrode clips and four covers with P/N 30137805.

For SevenGo™ meters one single electrode clip has P/N 51302325.

For FiveGo™ meters you get one electrode clip and two covers with P/N 30239144.

What is the difference between the FiveGo™ and the Seven2Go™?

From a specification point of view the Seven2Go:

  • has a measuring range of pH -2 ... 20 (instead of 0...14)
  • has a user-defined buffer group
  • can measure relative mV
  • can calibrate with up to 5 points (instead of 3)
  • offers segmented calibration mode
  • offers larger temperature range
  • can do timed interval readings
  • has a fast endpoint criterion (not only normal)
  • supports ISM
  • can be repaired, updated, calibrated, certified, adjusted

 

Some non-technical points:

  • The Seven2Go' s carry case uGo™ is more complete, robust, and to wash compared to the FiveGo™ carry case.
  • Portfolio of IP67 sensors of InLab® series (for Seven2Go™) is bigger and higher in quality than the IP67 sensors of LE series (for FiveGo™).
