Omega Engineering 2 channel handheld humidity k type thermocouple datalogger

the hh311 is a low cost, high performance handheld meter. it offers a triple display to show the temperature and humidity from a handheld probe and can display data from a separate k type thermocouple connected via a standard smp type miniature connector to the t2 input. the temperature/humidity probe uses a semiconductor and polymer capacitive sensor. an optional software package is offered to allow data to be read by a pc through the rs232 port. range: zero to hundred percent rh, -twenty to sixty°c (-four to one hundred and forty°f) t2 range: -two hundred to one thousand, three hundred and seventy°c (-three hundred and twenty-eight to two thousand, four hundred and ninety-eight°f) resolution: zero.one (except t2 for -two hundred > t2 > two hundred) accuracy: ±two.five percent rh at twenty-five°c, ±zero.seven°c (±one.four°f) t2 accuracy: ±[zero.five percent rdg ±one°c (two°f)] humidity response time: seventy-five sec in slowly moving air t1 response time: forty sec in slowly moving air meter dimensions: one hundred and eighty-six h x sixty-four w x thirty mm d (seven.three x two.five x one.two') probe dimensions: one hundred and ninety x fifteen mm (seven.five x zero.six'), cable stretches to one.five m (five') operating environment: zero to fifty°c (thirty-two to one hundred and twenty-two°f), zero to ninety percent non-condensing storage environment: -ten to sixty°c (fourteen to one hundred and forty°f), zero to eighty percent non-condensing power requirements: one 9v battery (included), ac adapter nine vdc ten ma min plug diameter: three.five x one.thirty-five mm rs232: nine thousand, six hundred bps, n, eight, one serial interface battery life: approx one hundred hours with alkaline battery weight: approx three hundred and twenty g (eleven.three oz)
