The high-performance compound microscope for every laboratory with fixed, pre-centred Koehler illumination.

The KERN OBF and OBL models are excellent, stable laboratory microscopes for all common routine applications
Through the simple Köhler lighting, the adjustable field diaphragm and a pre-centred and height-adjustable Abbe condenser with adjustable aperture diaphragm, these microscopes produce superb images in both the light and dark field
As standard, these microscopes, depending on the model, are fitted with wide-field eyepieces, achromatic, planachromatic or infinitely corrected E-Plan lenses
These binocular microscopes are fitted with a dioptre compensation
A trinocular head is available as an option, so that you can connect a camera
A revolving unit for up to 4 lenses and a large specimen stage are included with delivery as standard
The following optional accessory items are available: Various eyepieces, lenses, a complete polarisation kit, a phase-contrast unit as well as complete HBO and LED fluorescence kits etc.
The light is provided by a 20 Watt halogen lighting unit or by a 3 Watt LED version as an alternative
A central feature of this adaptable, robust microscope range is the stable mechanism which can be adjusted precisely

Manufactured from hardened stainless steel with dual reading in Imperial to 0.001in and in Metric to 0.02mm. The universal four-way measurement facility enables reading in External, Internal, Depth and Step modes.
The sliding thumb lock feature easily allows quick and precise measurements to be taken.
The satin finished scales and beam ensure fast, easy and accurate readings.
A strong plastic storage case provides a secure home for this precision instrument

There is a microprocessor chip inside the meter and the appearance of meter looks nice with easily operation.For notable features read as follows:
1)Large LCD with white background can display both pH and temperature value a the same time.
2)It has intelligent functions for automatic calibration,automatic temperature compensation,data storage/recall,memory max. and min. value etc.
3)Automatically display the percentage of slope after finishing calibration.
4)ºC and ºF can be switched freely.
5)Equipped with Model 600 electrode holder and calibration buffer solution,which is more convenient to use.
