The AM8917MT4A is a feature-packed microscope integrated with coaxial light and EDOF, answering needs for inspecting reflective surfaces and capturing all-in-focus images under 400x magnification. AM8917MT4A includes advanced features such as DPQ, EDR, AMR, and both Auto and Manual Refocusing.

With the use of the latest, cutting-edge optics, a brand new 5 megapixel sensor and several special features such as flexible LED control (FLC), Automatic Magnification Reading (AMR) and full aluminum body, the Dino-Lite AF7515MZT is a marvel of technology and the best choice for the high-demanding professional. The Dino-Lite AF7515MZT offers superb image quality and color reproduction in a robust, compact and appealing housing.

The AF7515MZT is part of the universal range and with its standard working distance and wide magnification range from 10 – 220x, it is suitable for a wide range of applications. Because of the built-in polarization filter this model is ideal when working with shiny or reflective objects such as metal, plastic, glass, jewelry, electronics, etc. The AMR function is of particular importance when the measurement functions are frequently used.

The Go Direct Salinity Sensor easily and precisely measures the total dissolved salt content in an aqueous solution. You have the ability to measure temperature-compensated salinity or non-temperature-compensated salinity, along with temperature. Measure water with a wide variety of salinities, from brackish water to ocean water, and even hyper-saline environments. You can also study how salinity affects buoyancy or monitor salinity values in estuaries where freshwater mixes with ocean water.

It features a built-in temperature sensor to simultaneously read salinity and temperature. Automatic temperature compensation allows students to calibrate the probe in the lab and then make measurements outdoors without temperature changes affecting data. This temperature compensation can be turned off to perform salinity studies as a function of temperature.

Remote Data Logging—Go Beyond Wireless Limits!

This Go Direct sensor is capable ofremote data logging! This feature allows sensors to store data directly to their internal memory—ideal for investigations that extend beyond typical connection ranges like long-term environmental monitoring or rocket launches. It works seamlessly with our award-winning Vernier Graphical Analysis^®app so students can visualize their data and make key connections between abstract science concepts and real-world phenomena.

The Go Direct Soil Moisture Sensor is used to measure the volumetric water content of soil. This makes it ideal for performing experiments in courses such as soil science, agricultural science, environmental science, horticulture, botany, and biology. This probe connects via Bluetooth^® wireless technology or via USB to your device.

The Go Direct Soil Moisture Sensor uses capacitance to measure the water content of soil (by measuring the dielectric permittivity of the soil, which is a function of the water content). Simply insert this rugged sensor into the soil to be tested, and the volumetric water content of the soil is reported in percent.
