Crowcon Gas-Pro - Increased Gas Sensor Range

The Crowcon Gas-Pro is the newest member of the Crowcon personnel gas monitor range. Although only launched a few months ago, many customers have converted over to this superb instrument.

As discussed in my original blog ‘Confined Space Entry – is your gas detector right for the job?’, the Crowcon Gas-Pro has been designed to allow more sensor to be utilised with the instrument will less cross sensitivity or conflict. With the introduction of further sensors, the instrument can be configured for a wider range of applications other than confined space.

Leica Sprinter Frequently Asked Questions

Frequently asked questions about Leica Geosystem's range of Leica Sprinter digital levels


What are the main advantages of an electronic level compared to an optical one?
With optical levels it happens many times that you do not read out correctly. The electronic level eliminates such errors. Furthermore, digital levels such as the Leica Sprinter 150 / 150M / 250M automatically calculate the height differences based on your measurements.

What is the typical measuring time?
For all models, the typical electronic measuring time is 2-3 seconds in normal daylight condition. Measuring time will be slightly longer with uniform dim light condition, for instance in the late evening or under a street light at night.

What is the accuracy of the Leica Sprinter models?
The ISO double-run electronic accuracy for Leica Sprinter 50 / 150 / 150M / 250M are 2.0mm / 1.5mm / 1.5mm / 1.0mm respectively. For all the models, the ISO double-run optical accuracy is 2.5mm.

What is the shortest focusing distance?
The shortest optical focusing distance is 50 cm for all of the models. This short focusing distance comes in handy when working in a narrow confined space.

What is the maximum measurable distance?
All of the models are able to measure electronically from 2 m to 100 m with a Sprinter standard aluminum barcode staff.

Does the Leica Sprinter only operate with Lieca Sprinter GSS staffs?
Yes, the attached barcode on GSS staffs is only valid for Leica Sprinter.

What are the onboard functions available for Leica Sprinter 50?
Leica Sprinter 50 is the basic ‘one-touch’ model available with Height & Distance measurement capability, on-board electronic Line of Sight Adjustment program, auto-recognition of staff orientation, tilt warning and preset units setting in meter or US feet (regional dependent).

What are additional features of the Leica Sprinter 150?
Leica Sprinter 150 is a medium range model available with Height-Difference measurement capability and operating functions such as LCD display contrast, units, auto-off, rounding, audio beep, tilt warning, LCD display back light, measurement averaging and MMI language selection can be easily access via the user-friendly menu.

Does the Leica Sprinter instruments have onboard data storage?
Yes, Leica Sprinter 150M and 250M are able to store measured field data to the onboard storage.

What are additional features of the top range Leica Sprinter 150M / 250M?
Leica Sprinter 150M / 250M are the more advanced models with onboard and well-guided applications such as line leveling, cut & fill and timer function for monitoring work. Measurement can be recorded to the onboard storage or externally to a data logger via RS232 cable. Onboard stored data can be easily downloaded directly to a PC via USB cable. One click and the data is transferred immediately to Microsoft Excel.

What is the main purpose of the internal memory of the Leica Sprinter 150M / 250M?
If you execute a line leveling or an area leveling job, you do not have to write down all measurement results. This saves a lot of time. Furthermore, back in the office, you just transfer your data from the instrument storage directly into Excel where all results are presented in appropriate order for post-processing.

How can the data be downloaded from Leica Sprinter?
Measurement data can be downloaded from Leica Sprinter 150M / 250M to PC:
A) via Leica Sprinter USB cable to Leica Sprinter DataLoader
B) via RS232 cable to Leica Geo Office LGO or Microsoft Hyper-terminal program

In which PC operating system environment the Leica Sprinter DataLoader is executable?
Leica Sprinter DataLoader is executable on Microsoft Windows Vista, XP, 2000 and 98.

For data downloading, can this data be downloaded with all versions of Microsoft Excel?
Data can be downloaded to Excel versions 2007, 2003, 2002 and 2000 (versions 12 - 9.0).

What is the idea of the new Cut & Fill application on Leica Sprinter 150M and 250M?
This very useful onboard application will help you to check heights compared to a design level. For example, excavation: The print indicates the designed excavation level. You can now check easily if the designed level is already achieved by taking measurements. The software will immediately present cut and fill results (height differences between design level and measured height).

Any protection against water, dust and sand?
Yes, All the Leica Sprinter models meet the environment specification IP55 (IEC 60529) for protection against water, dust and sand.

Can I use an external power supply for Leica Sprinter instead of 4 AA dry cells?
Yes, you can power Leica Sprinter 150M / 250M with GEV71 external power pack with RS232 cable from Leica Geosystems.

How long can 4 AA dry cells last with continuous operation of the instrument?
In normal ambient temperature, 4 AA alkaline cells will last for at least 8 hours of continuous operation of the instrument.

Crowcon Tetra3 Extended

Gas detection specialist Crowcon has expanded the capabilities of its Crowcon Tetra:3 (T3) personal multi-gas detector with three more toxic gas sensors: ozone (03), sulphur dioxide (S02) and ammonia (NH3).

This complements the existing sensor range which includes flammable gases, oxygen (02), hydrogen sulphide (H2S), and carbon monoxide (CO).

The new sensors widen the applications for the Crowcon Tetra3 to include the chemical, pharmaceutical, food and beverage processing industries, as well as water and wastewater treatment facilities.

Featuring a top-mount display and the capacity to detect up to four gases at once, the Crowcon Tetra3 is designed for use in the most demanding industrial environments, including confined space work. It features intuitive, single button operation, essential for users with gloved hands.
