HI 99550 is used for non-contact measurement of the temperature of non-metal objects. Suitable for the non-contact measurement of temperature of food, chemicals, plastics, paper, wood, glass, rubber, metal coated materials, etc.

MC74AC132/74ACT132 Four-input NAND Schmitt Trigger

The HI 993310 is a portable water conductivity and soil activity meter that allows for quick and simple measurements of soil activity, conductivity of irrigation water, nutritive solutions, and saturated soil-paste. The meter comes with two probes: HI 76305 with a stainless steel conic tip for direct soil measurements, and HI 76304 for fertilizer enriched solutions. The meter has two LED indicators for displaying the tested parameter and an alarm LED that lights up if the soil is too dry or lacking nutrients. Calibration for conductivity measurements can be done using a knob on the front of the meter, and the soil activity measurements are calibrated through conductivity calibration. Temperature affects conductivity measurements, while soil activity depends on soil texture and hydric property; both probes include a temperature sensor for automatic temperature compensation.

MC74AC126 and MC74ACT126 are Quad Buffer with 3-State Outputs, support TTL compatible inputs and 3-state enable input, the maximum operating voltage is 7V, the maximum input current is 20mA, the maximum output current is 50mA.

This document describes the features and characteristics of the MC74AC125 and MC74ACT125 products. They are quad buffers with TTL compatible inputs and outputs, featuring high voltage level, low voltage level, and high impedance outputs. The document also provides maximum ratings and recommended operating conditions.

This manual provides detailed instructions on how to use the Hanna HI 9931 and HI 9934 wall mounted conductivity and TDS controllers.

MC74AC113/74ACT113 is a high-speed independent triggered JK dual D flip-flop

This document describes the specifications and features of the HI 99300 and HI 99301 portable instruments, including measurement ranges and resolutions for EC, TDS, temperature, automatic calibration and compensation, and warranty information for use and maintenance.

The MC74AC112/74ACT112 consists of two high-speed completely independent transition clocked JK flip-flops. The clocking operation is independent of rise and fall times of the clock waveform. The JK design allows operation as a D flip-flop (refer to MC74AC74/74ACT74 data sheet) by connecting the J and K inputs together. Asynchronous Inputs: LOW input to SD (Set) sets Q to HIGH level LOW input to CD (Clear) sets Q to LOW level Clear and Set are independent of clock Simultaneous LOW on CD and SD makes both Q and Q HIGH • Outputs Source/Sink 24 mA • ′ACT112 Has TTL Compatible Inputs CP VCC CP1 K1 J1 SD1 Q1 Q1 CD1 CD2 CP2 K2 J2 SD2 CD J Q Q2 SD CONNECTION DIAGRAM Q2 GND 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 K Q CP SD K Q CD J Q MODE SELECT — TRUTH TABLE Operating Mode Inputs Outputs Operating Mode SD CD J K Q Q Set L H X X H L Reset (Clear) H L X X L H *Undetermined L L X X H H Toggle H H h h q q Load “0” (Reset) H H l h L H Load “1” (Set) H H h l H L Hold H H l l q q H, h = HIGH Voltage Level L, l = LOW Voltage Level X = Don’t Care l, h (q) = Lower case letters indicate the state of the referenced input (or output) one set-up time prior to the HIGH to LOW clock transition. *Both outputs will be HIGH while both SD and CD are LOW, but the output states are unpredictable if SD and CD go HIGH simultaneously.

This document describes the features and characteristics of Hanna Instruments' portable waterproof skin pH meter, including measurement range, resolution, accuracy, temperature compensation, etc.

The document is an instruction manual for the HI 99171 portable waterproof leather and paper pH meter. All Hanna Instruments meters are covered by a two-year warranty, with the probes having a warranty period of six months. The warranty includes free repair or replacement, but does not cover damage caused by accidents, misuse, tampering, or lack of maintenance as instructed. If service is required, the instrument should be taken to the dealer from whom it was purchased, and relevant information such as model number, purchase date, serial number, and nature of the problem should be provided. If the repair is not covered by the warranty, the customer will be informed of the incurred charges. If the instrument needs to be returned to Hanna Instruments, a Returned Goods Authorization Number should be obtained from the Customer Service department, and the shipping costs should be prepaid. Proper packaging for complete protection is advised when shipping the instrument.
