Partial Immersion, Single Scale Range -20/110 degrees C, Scale: 1 Degree, 300mm Length Partial immersion is best for most applications. These thermometers are calibrated to read correctly when only 3" of the stem is immersed in the liquid being measured. Total immersion thermometers are calibrated for use when the entire liquid column is totally immersed in the substance being measured and should be used under those circumstances. All of our thermometers are made to SAMA specifications for ranges and accuracy. In addition, each of our thermometers has a number of extra quality features built into each one: REINFORCED BULBS, to prevent breakage, RING TOPS, for submersion, NON ROLL CAPS, SCALES PRINTED INTO THE GLASS, rather than on the surface so they never wear off.

A very simple, easy and economical way of measuring melting points. The apparatus consists of an aluminum block 2.5" (62mm) in diameter by 2" (50mm) high, with a slanted hole to accept a thermometer. The testing material is sprinkled on the top of the block and the block is heated with a heat source like a bunsen burner. As soon as the material starts to melt the reading on the thermometer is the melting point. This apparatus can be used to measure melting points upto 250 degrees C. Stand and thermometer not included.

This construction set teaches the basics of hydraulics through play. The fischertechnik hydraulic system is operated with water, demonstrating how force can be transmitted via liquid media. Here’s how the system works: A manually operated control cylinder presses the water into the working cylinder through hoses. The working cylinder extends, moving the digger arm or the shovel on the powerful crawler excavator. This allows builders to control three different excavator movements hydraulically. Five different models can be built with the PROFI Hydraulic construction kit, meaning this new kit offers extensive building and playing fun. Combined with additional pedagogical materials on the eLearning Portal, this construction kit truly lets students “Learn about technology through play”.
Additional instructional materials:
The following are available for free download from the fischertechnik eLearning portal: Didactic material.
Product contents:
Total of 475 parts, including 8 x hydraulic cylinders, 4 x control cylinders and 1 x printed building manual included,1 x didactic materials available online and 1 x sturdy storage box with cover sheet and list of parts.
