Monitor the direction strength of a magnetic field at a particular location. Alerts you when a selected value is reached using visual &/or sound &/or vibration. Synchronizes to a specific signal (x, y, z or magnitude) in 4 different modes: falling edge, rising edge, low state and high state. Records the measurements from 100 to 10000 shots, plot, read and can be sent by Email as a CSV type. Several measure acquirements time base from 0.1 measure/second to 10 measures/second. Display the measurements in µTesla or mGauss unit. Automatic resizing screen. Extremely light weight app. Nota: It is not suitable for iPod which doesn’t have embedded magnetic field sensors. 监测特定位置的磁场的方向强度。 使用视觉和/或声音和/或振动达到所选值时提醒您。 以4种不同的模式同步到特定信号（x，y，z或幅度）：下降沿，上升沿，低状态和高状态。 将测量记录从100到10000记录，绘制，读取，并可以通过电子邮件发送为CSV类型。 几个测量时间基准从0.1测量/秒到10次/秒。 以μTesla或mGauss单位显示测量值。 自动调整大小的屏幕。 翻译为8种不同的语言：英文，法文，西班牙文，意大利文，葡萄牙文，德文，俄文和简体中文。 极轻的应用程序 注意事项：不适用于没有嵌入式磁场传感器的iPod。 监测特定位置的磁场的方向强度。 使用视觉和/或声音和/或振动达到所选值时提醒您。 以4种不同的模式同步到特定信号（x，y，z或幅度）：下降沿，上升沿，低状态和高状态。 将测量记录从100到10000记录，绘制，读取，并可以通过电子邮件发送为CSV类型。 几个测量时间基准从0.1测量/秒到10次/秒。 以μTesla或mGauss单位显示测量值。 自动调整大小的屏幕。 极轻的应用程序 注意事项：不适用于没有嵌入式磁场传感器的iPod。 Surveille la force directionnelle d'un champ magnétique à un endroit particulier. Avertit lorsqu'une valeur sélectionnée est atteinte: Visualisation et / ou son et / ou vibrations. Synchronise les acquisitions avec un signal spécifique (x, y, z ou magnitude) dans 4 modes différents: front descendant, front montant, état bas et état haut. Enregistre les mesures de 100 à 10000 salves, trace, relit et peut envoyer un Email au format CSV. 5 bases de temps sont possibles. De 0,1 mesure / seconde à 10 mesures / seconde. Affichage des mesures en μTesla ou mGauss. Redimensionnement automatique de l’écran. Application extrêmement légère. Nota: Ne convient pas aux iPod car ils sont dépourvus de capteurs de champ magnétique. ## Key features - Magnetic field strength and direction monitoring - Customizable alerts (visual, sound, vibration) - Data recording and plotting - CSV export via email - Adjustable measurement rates - Multiple display units (µTesla, mGauss) ## Recent user reviews (4 of 4) All indexed reviews: https://appshunter.io/ios/app/gauss-tesla-meter/id1248096214/reviews.md ### 5/5 — Performs as described. I would buy again. *2021-12-09* Works as described. I’m trying to detect a spike in Tesla units to help explain a mysterious signal from my ICD. ### 3/5 — I wish I knew... *2021-04-04* I wish I knew the readings meaning. How do I know where high Tesla is coming from? Is it cell or satellite or?? ### 5/5 — Good app *2019-06-15* Work 👍🏻 great. **Developer response:** Thanks for your revise and good feedback. Wish your enjoy using it for long. Stef ### 5/5 — Easy interface to understand, even for novices *2017-12-28* I’m not an expert by any means in these particular types of sensor metrics reading, but I can definitely see how different sources of electromagnetic energy affect the meters on my iPad Air. The program is great for what it does, simple tasks of metering and monitoring. ## Frequently asked questions about Gauss Tesla Meter ### What is Gauss Tesla Meter used for?
