Pumping up math and science in our nation’s high schools is high on educators’ agenda … but buying lab computers isn’t. So Pasco Scientific has designed an inexpensive, handheld digital device that’s priced right … and they’re shipping their 1st 1000 units this month, with back orders for the next run. Their device, called a GLX, lets students take readings on water temperature, ph levels, dissolved oxygen and other measures as they walk in class … and the results are instantly graphed on the handheld screen. It costs only $300, far less than computers. Pasco hopes to sell 10,000 by next year.
