ZIPLEVEL® GEOTECH
-
The ZIPLEVEL GEOTECH is a precision pressurized hydrostatic altimeter created directly from the proven ZIPLEVEL PRO-2000 technology. Unlike the PRO-2000, the GEOTECH keeps the measurement module electronics fixed within its base unit reel hub while its compact reference cell moves freely as a sensor. The difference in elevation between the sensor and the base unit is displayed directly in digits with all the powerful functions, reliability and ease of use of the ZIPLEVEL PRO-2000.

Imaging & Analysis
-
Microscopes offered by Buehler generally fall into the categories of stereo microscopes, upright microscopes, or inverted microscopes. Inverted microscopes are commonly referred to as metallurgical microscopes. Microscopes may offer episcopic (reflected light) observation, diascopic (transmitted light) observation, or both possibilities. Illumination may be delivered in bright field mode (BF) or dark field mode (DF), and several techniques such as differential interference contrast (DIC) and polarized light microscopy make use of the nature of light to reveal specific pieces of information when studying materials.

Digital Tank Test Kit
4109
-
The voltmeter included in the kit, the “Model DPM” voltmeter, is designed for ease of use by meter readers and corrosion technicians alike and the voltmeter comes with an integrated RE-5 reference electrode attached for “metallic structure-to-soil” potential difference readings. The kit also includes a special test lead that has a brass thumb screw on one end which allows the test lead to substitute for the RE-5 reference electrode. This substitution allows the voltmeter to take “structure-to-structure” potential difference readings. The voltmeter offers two ranges, ±2VDC and ±20VDC with a 20MΩ input impedance. Since the voltmeter is digital [in contrast to the meter in our analog tank test kit (Cat. # 4108)], both negative and positive voltages are displayed. `
