It is widely used in gas pipeline leak detection, household gas prevention, gold mine field, tunnel mine operation oil and gas exploitation field, dangerous goods storage warehouse, etc.
Standard industrial design, fast response, double alarm.
Scope of application: can test 74ch series, osmo series, cd4000 series, hef400 series, 4500 series, operational amplifiers, interface chips, optocouplers, automatic transistor identification, voltage regulator voltage identification
Integrate more than 1,300 types of chip data models and more than 420 types of transistor data models, covering most common general-purpose devices within 24 pins, which can greatly reduce maintenance workload and improve work efficiency
Press the Enter key to turn on the machine for the first time and automatically run a self-test. The self-test detects the battery voltage and displays it on the screen after more than two seconds. When the battery voltage is lower than 7v, replace the battery to ensure the measurement accuracy. If If there is no alarm, the measurement work can be started
Nativead 10 ad, the theoretical resolution of 5v voltage is 0.0048v
Due to the use of batteries for power supply, it is not suitable for measuring high-power thyristors
The Zener value must be based on the actual measurement, not just the nominal value
The default directory for initialization is the search directory
Different test modes: 5v mode, 3.3v mode, auto mode
Frequency measurement: TA802A: 40Hz-6MHz, TA802B: 40Hz-9.9MHz
Resistance measurement: 0.1 ohm-60 megohm
Display: up to 6000 counts
Function: logic level (TA802B does not have this function), NCV measurement, zero/fire wire measurement, automatic shutdown, backlight display, flashlight lighting
Equipped with Silicon Labs' clock generators, TDK capacitors and STMicroelectronics with an accuracy of 1/25" and a measurement range of up to 131 feet to meet your routine measurement needs.
Easy to use:
Simple one-button operation - Press the button once to start the measurement. With a weight of 28 grams, this laser measurement is compact and can be placed in any pocket. With a backlit color display, measurements can be easily read even in dark environments.
DURABLE:
The laser distance measurement is IP54 and can withstand harsh site conditions such as dust; 3,000 measurements per charge.
2.0-inch smart screen, and added the test attributes of the smart multimeter. At the same time, it optimizes the use of functions and the testing experience. And added a "strong sensitivity detection mode" design.
The clear EBTN display is clear and easy to read.
Non-contact and pen-shaped design, easy to operate and carry.
Dual mode operation (low sensitivity and high sensitivity)
It has dangerous voltage induction alarm, DC/AC voltage, resistance, frequency, line/zero line difference, line breakpoint position, continuity check, flashlight characteristics, etc.
It has 8 LED indicators in 3 colors (red/yellow): automatic identification of high/medium/low voltage.
Alarm mode: sound, analog bar and indicator light (red/yellow).
LED spotlight, low battery prompt, automatic shutdown function.
Packing method: Sealed with plastic film, each pack / 80 sheets with standard color card
Effective range: 1-14
Method of use: drop or smear the liquid to be tested on the PH test paper, it can be reflected and displayed almost without waiting, and then compared with the attached standard color chart to get the PH value.
How to use pH test paper 1-14
Step 1: Open the strip-shaped piece of paper exposed by the test bag, the paper sheet is pH test paper, and there are 1-14 color cards on the surface of the box.
Step 2: Remove the test strip and place it flat on a dry glass or plastic sheet (Note: the glass or plastic sheet must be dry and clean);
Step 3: Use a glass rod or pipette to take the test solution and drop it on one end of the test paper;
